Pain on the SIDE of your hip?
They told you it's bursitis. Or arthritis. Or "just your age." It's probably a squashed tendon.
That deep ache on the outside of your hip, the one that won't let you lie on that side, is most often your glute tendons pinned against the bony point of your hip. And almost everything you've been told to do keeps squeezing them.

The most misdiagnosed hip pain in women over 50? Gluteal tendinopathy.
Gluteal tendinopathy is irritation of the glute tendons right where they attach to the bony point on the outside of your hip. It is the most common cause of pain on the side of the hip, and nearly 1 in 4 women aged 50 to 79 has this kind of pain (Archives of Physical Medicine and Rehabilitation, 2007).
But here's what happens, over and over: it gets written off as "bursitis" or "arthritis" without anyone ever checking the tendon.
When radiologists ultrasound-scanned 877 people sent in for pain on the side of the hip, about 8 out of 10 had NO bursitis at all. The most common thing they did find was damage to the glute tendons. (American Journal of Roentgenology, 2013)
Read that again. 8 out of 10.
And an X-ray can't see a tendon. At all. So it finds a little wear in the joint, and the joint takes the blame.
Simply put: nobody can calm a tendon if nobody tells you it's a tendon.
Here's what most doctors get wrong
It's not a "bursitis" problem. It's a squeeze problem.
Your glute tendons attach on the bony point on the outside of your hip. Over the top of them runs a thick band of tissue down the outside of your thigh, like a tight strap.
Every time your thigh drifts across your body, that strap presses the tendons into the bone. Every time you lie on that side, your whole body weight does the same thing. For hours.
Squeezed against bone day after day, the tendons get irritated, thickened and sore to touch. And tendons don't get much blood flow to begin with, so once they're cranky, they stay cranky.
Tap the moment that hurts you:
It hurts to lie on that side at night?
Your body weight pins the tendon against the bone for hours. Roll onto the other side and your top knee drops, which pulls the strap tight over the sore one. That's why there's no comfortable side left.
The stairs feel like a mountain?
Every step up puts your whole body weight on one hip, and your glute tendons have to hold you level. A cranky tendon complains on every single step.
It aches when you cross your legs?
Crossing pulls your thigh across your body, which drags the tendon tight over the bony point and holds it there.
Standing at the sink sets it off?
Most of us stand with our weight sunk into one hip. That hip drops out to the side and the strap squeezes the tendon, minute after minute.
There's one spot you can press and say "there"?
That bony point is where the tendons attach. A sore spot right on it is one of the clearest signs it's the tendon, not the joint. Hip-joint arthritis usually aches deep in the groin instead.
Try the 30-second check tonight
- Stand on your sore leg for 30 seconds.
- Press the bony point on the outside of your hip.
- Lie on that side.
If two of the three bring on that familiar ache, the glute tendons are the usual suspect.
The bad news?

✕Calms it for a few weeks, then it creeps back
✕A year later, barely better than doing nothing

✕The ache comes back the moment the pill wears off
✕Every day, for years, on your stomach
Most doctors reach for the same old toolbox: pills and cortisone shots. The problem? Both only turn the volume down. Neither one takes the squeeze off the tendon.
In 2018 the British Medical Journal published a trial on exactly this problem. 204 people with gluteal tendinopathy got a cortisone shot, lessons on how to stop squeezing the tendon plus simple daily exercises, or nothing at all.
A year later, 57% of the people who got the shot said they were better. The people who got NOTHING? 52%.
The group that did best, by a mile, was the one that learned to stop squeezing the tendon: 78%.
Shots buy weeks. Taking the pressure off is what lasts.
But nobody hands you that lesson. Because there's no repeat business in a tendon that calms down at home.
And if you think stretching it and rolling it will help... guess again.
Every hip video on the internet shows the same stretch: pull your knee across your body and lean into it. For this tendon, that's the exact position that drags it tight over the bone.
The foam roller on the outside of your thigh? You're grinding a sore tendon into bone and calling it therapy.
The expensive new mattress? You're still lying on the sore spot.
A cranky tendon needs 3 things to settle down:
Legs uncrossed, weight on both feet, never lying on the sore side.
Brought back into the tissue around the tendon.
Not once every few months in a doctor's office.
Introducing the Daywick 4-in-1 Hip Therapy Belt: relief that sits right on the sore tendon
Deep heat, red light, gentle vibration and compression in one wireless belt. The wide panel covers the whole outside of your hip, from your waist to halfway down your thigh, so the bony point sits right in the middle of it.
Press one button, sit back with your legs uncrossed and give that tendon 15 quiet minutes. It works on either hip.
Unlike shots and pills that just turn the volume down, the belt works right where it hurts, every day, in your own chair.
"They called mine bursitis. Is this still for me?"
Yes. The label isn't what hurts. If your pain sits on the bony point on the outside of your hip and it's worse when you lie on it, the same thing calms it: take the pressure off and soothe the tissue right on that spot.

Still deciding? Read the top questions women ask before ordering
Is it bursitis or a tendon? Does it matter?
On ultrasound, about 8 out of 10 people with pain on the side of the hip have no bursitis at all, and the glute tendons are the most common finding. Either way, if the ache sits on the bony point and it's worse when you lie on it, the same routine applies: take the pressure off and calm the tissue.
Does it work on either hip?
Yes. It's the same belt for the left or the right hip.
How long do I use it each day?
15 minutes at a time. It switches itself off. The instructions point to results over 14 to 30 days of daily use.
Can I sleep in it?
No. Use it while you're awake, then take it off before you sleep.
Is it wireless?
Yes. It's rechargeable with the included USB-C cable. It doesn't heat or vibrate while it's charging, so charge it first and then use it cordless.
I've had hip surgery. Can I use it?
Check with your surgeon before using any therapy device after an operation.
Who should ask a doctor first?
If you're pregnant, have a pacemaker or another implanted device, reduced feeling in the skin, or any medical condition, ask your doctor before using it.
What if it doesn't work for me?
You're covered by our 30-day money-back guarantee. Email our support team and we'll get your money back.
Can I buy it on Amazon?
No. It's not sold in stores or on Amazon, only on the official Daywick website.
When will it arrive?
Shipping is free, and orders are delivered in about 5 to 8 business days.
It's not your age. It's not your joint. It's a tendon, and it has been squeezed long enough.
