It isn't arthritis. It isn't wear and tear. It has a name.
Solva is a wearable red light therapy device designed for one specific problem: the gluteal tendinopathy that develops in women after the menopause.

Three GPs, eighteen months of waiting, and nobody actually told you what's wrong.
The hip started aching somewhere around the time the periods got irregular. Not in the groin. On the outside. The side you can't sleep on.
You went to your GP. You were told it's "wear and tear"...
- The scan came back clear. Or showed "mild age-related changes".
- NHS physio waiting list: nine months.
- Private physio at £60-80 a session. Helps. Stops helping...
- Cortisone. Helps for six weeks. Each injection works for a shorter time...
You're now eighteen months in. And nobody has actually told you what's wrong with you.
It's called gluteal tendinopathy. And it's almost certainly hormonal.
Gluteal tendinopathy is the breakdown of the tendons that anchor your buttock muscles to the side of your hip bone. Those tendons sit on the outside of the hip — exactly where your pain is.
It's invisible on a standard X-ray, because tendons are soft tissue and soft tissue doesn't show up on imaging. That's why your scan looked clear.
Here's what nobody connects: oestrogen is the primary signal your body uses to tell tendons to produce collagen. When oestrogen drops at menopause, that repair signal weakens. Daily micro-damage starts accumulating faster than it can be repaired. Within twelve to twenty-four months, the tendon starts to break down.
The timing isn't a coincidence. It's exactly what the biology predicts.
Three wavelengths. One job: restart the repair signal your body stopped sending.
solva uses photobiomodulation — specific wavelengths of red and near-infrared light that stimulate the mitochondria inside your tendon cells. The same energy factories that produce collagen. In effect, the light replaces the hormonal signal your falling oestrogen has stopped sending.
Surface circulation
660 nm · Red lightPenetrates the skin and fascia surrounding the hip. Improves micro-circulation to the outer hip and prepares an oxygen-rich pathway for the deeper wavelengths to work in.
Cellular energy
830 nm · Near-infraredReaches the gluteal tendon at depth. Stimulates the mitochondria inside the tenocytes — the cells responsible for producing collagen — and triggers ATP synthesis, the cellular currency for repair.
Deep tissue repair
940 nm · Deep infraredThe deepest-penetrating wavelength. Calms underlying inflammation and supports the structural alignment of new collagen fibres as they're laid down by the now-active tendon cells.

Wrap it around your hip
The double-strap system positions the LED panel directly over the outer hip — exactly where the gluteal tendons attach. Adjustable to fit waist 70–120cm and thigh 45–75cm. Works over leggings or directly on skin.
Press the button. Sit down.
One button to switch on. solva runs a 20-minute treatment cycle and automatically switches off when it's done. Wear it while you read, watch television, work at your desk, or scroll your phone.
Do it once a day, every day
Tendon repair is a daily process. Consistency over six to twelve weeks is what produces the change — not intensity in a single session. Most women report meaningful change inside the first six weeks.
What to expect, week by week
The first signs of change
Increased blood flow to the outer hip becomes noticeable. Many users describe a "warming" sensation during sessions. Sleep quality begins to improve as overnight pain interruptions reduce.
Pain levels start to ease
As mitochondrial activity in the tendon cells rises and collagen synthesis ramps up, daytime pain typically reduces. Sitting for longer becomes easier. The "ache after standing up" softens.
Structural repair compounds
Tendon tissue continues to rebuild on the cellular level. Most women using solva consistently report being able to lie on the affected side at night again. Walking and stairs no longer dictate the day.

If three of those signs match, you've been told the wrong thing.
solva is the device designed to address the actual cause, not the label your GP gave it.
Order solvasolva vs every other thing you've already tried.
| PAINKILLERS / NSAIDS | CORTISONE INJECTIONS | GENERIC PHYSIO | solva | |
|---|---|---|---|---|
| Targets the actual cause (tendon breakdown) | No | No | Partly | Yes |
| Drug-free, no systemic side effects | No | No | Yes | Yes |
| Works long-term, not just for weeks | No | No | Variable | Yes |
| No appointments, no waitlists | Some | No | No | Yes |
| Doesn't weaken the tendon over time | Neutral | No | Yes | Yes |
| One-time cost, no monthly fees | No | No | No | Yes |
What you've already spent — and what comes next if nothing changes.
If you've been dealing with this for two years, you've almost certainly already spent more on partial fixes than solva costs once. And the curve gets steeper the longer it goes untreated.

Use it properly. If it doesn't work, send it back.
Use solva daily for ninety days, the way it's designed to be used. If your hip pain hasn't meaningfully improved, return it for a full refund. We cover the return shipping. No questionnaires, no quibbles, no fine print. We're confident because the biology behind it is straightforward — but the responsibility is ours, not yours.
Everything women ask us before ordering.
What if my GP said I have arthritis, not gluteal tendinopathy?
You're not the first. A substantial proportion of women diagnosed with hip "arthritis" or "trochanteric bursitis" actually have gluteal tendinopathy — the conditions are routinely confused because they present in similar age groups. The defining clue is pain location: arthritis pain sits deep in the groin or thigh; gluteal tendinopathy pain sits on the outer hip, where the tendons attach. If your pain is on the outside and your scan came back clear, the maths doesn't add up to arthritis.
How long does it take to work?
Tendon repair is genuinely a slow process — there's no overnight version of it. Most women report the first noticeable change in sleep quality and overnight pain within the first one to two weeks. Daytime pain typically starts to ease between weeks two and four. Substantial structural repair compounds across weeks six to twelve. We ask you to commit to daily use for ninety days, which is what the 90-day guarantee is built around.
Can I use it on other parts of my body?
Yes. The wavelengths solva uses (660, 830 and 940nm) are well-studied for soft-tissue repair generally, not just for hip tendons. Many of our customers tell us they use it for lower back discomfort, knee soreness after exercise, or shoulder stiffness. Bear in mind that solva was designed specifically for the hip, and the strap system is shaped accordingly — for other body areas you may need to wear it differently.
What size does it fit?
solva uses an adjustable double-strap system designed to fit a waist measurement of 70–120cm and a thigh measurement of 45–75cm. It's one size and adjusts to fit the great majority of body types. If you fall outside this range, contact our UK customer support team before ordering — we'd rather talk it through than have you return it.
Can I wear it over clothes?
Yes, solva works over leggings or thin trousers. For best results — particularly in the first month — you'll get marginally faster effect with the panel directly against the skin, because less light is scattered before it reaches the tendon. But many women wear theirs over clothes during the day with no issue.
How does the 90-day guarantee actually work?
Use solva daily for ninety days the way it's designed to be used. If at the end of that period your hip pain hasn't meaningfully improved, email our UK customer support team and we'll arrange a full refund. We pay the return shipping. There are no questionnaires, no fine print, no charges for "wear and tear". This is the part of our offer that exists because we've seen what solva does in practice. The risk is ours.
How long until I receive it?
Standard UK orders are dispatched within one to two business days via tracked delivery. You'll receive a tracking link by email as soon as your order leaves our warehouse. Most UK addresses receive their solva within three to five working days of ordering.
Will it interfere with my HRT?
No. solva does not interact with HRT or any other medication — it doesn't enter the bloodstream or affect hormone levels directly. The light works locally on tendon tissue, stimulating the cellular machinery that produces collagen. Many women using solva are also on HRT and the two are complementary rather than conflicting. As with any health-related decision, if you have specific concerns, raise them with your GP.
What's in the box?
Your solva device with integrated triple-wavelength LED panel and adjustable double-strap system, a USB-C charging cable, a cotton carry pouch, and a quick-start guide. The Pair bundle also includes free access to "The Hip Pain Field Guide" — a 14-page PDF covering what tends to work, what doesn't, and a list of questions worth asking your GP.
It's not a complicated decision. It's just two options.
You close this page.
Six months from now, the hip is the same — or worse. Another GP appointment. Possibly another cortisone shot that helps for less time than the last one. The night-time pain interrupts your sleep three to four times a week. The walking has slowed. The Pilates class is something you've quietly stopped going to. Your body keeps trying to do what it can't do without the right signal.
You try solva for 90 days.
By week eight, the night-time pain has noticeably eased. By week twelve, sleeping on that side is something you stopped thinking about. You've taken back the walking. You're back at Pilates, or whatever the equivalent looks like for you. solva sits in a drawer, ready for a future flare-up. And the £99 has paid itself back in the appointments you no longer need.

P.S. If you've read this far, the symptoms probably matched. Three GPs, the clear scan, the cortisone that stops working, the physio that didn't help — none of this is in your head. It's just that nobody connected it to oestrogen and tendon collagen. Now you know. The next step is up to you.
P.P.S. The 90-day guarantee exists because tendon repair takes time and we don't want anyone giving up at six weeks. Use solva properly for the full ninety days. If it hasn't made a meaningful difference, send it back. We'll refund every penny, including the return shipping.
P.P.P.S. Most women who order solva tell us they wish they'd done it a year or two earlier — that the only thing they "lost" was the time spent waiting for the next intervention to work. If that's where you are now, the choice doesn't get easier with another six months of waiting.
