Will this work for my frozen shoulder ?

If you have shoulder pain that's worse at night, can't reach behind your back, or your doctor has mentioned frozen shoulder or adhesive capsulitis—yes, this is designed specifically for that condition. It addresses the root cause: scar tissue buildup from dropping estrogen.

How long until I see results ?

Most people report sleeping better within 2 weeks. Significant pain reduction typically happens by week 4, with major mobility improvement by week 8-12.

Everyone's different, but consistency is key—use it daily for 20 minutes.

Verified customer review

“Last year alone, I spent over £4,000 on treatments with little result. This device cost me less than two cortisone injections — and for the first time in years, I can finally sleep on my side again.

My orthopaedic specialist said surgery was only six months away. That was over a year ago.

If you're not sleeping through the night, moving pain-free, and living without constant shoulder pain, we'll issue you a full refund, no questions asked.

  • "I spent five months seeing different doctors, all telling me it was ‘just tendinitis’ and to take ibuprofen. The shoulder pain was affecting my sleep, and I couldn’t even tie my hair back. After using SiaaSoo for a few weeks, I finally started feeling like myself again — even my doctor was surprised by the progress.”

  • “Waking up around 2am every night because of shoulder pain was exhausting. I tried ice, painkillers, and even two cortisone injections, but nothing brought lasting relief. This is the first thing that’s helped me rest properly again — and finally get a full night’s sleep.”

  • “I’d started to accept that this pain was simply part of getting older. My shoulder felt so stiff that I had to drop my coat on the floor just to put it on. After around five weeks using SiaaSoo, I can reach overhead again, sleep on my side, and finally feel like myself.”

    Frequently Asked Questions

    Everything you need to know before ordering SiaaSoo.

    Will this work for my frozen shoulder ?
    If you have shoulder pain that's worse at night, can't reach behind your back, or your doctor has mentioned frozen shoulder or adhesive capsulitis—yes, this is designed specifically for that condition. It addresses the root cause: scar tissue buildup from dropping estrogen.
    How long until I see results ?
    Most women report sleeping better within 2 weeks. Significant pain reduction typically happens by week 4, with major mobility improvement by week 8-12. Everyone's different, but consistency is key—use it daily for 20 minutes.
    What if it doesn't work for me ?
    You have 90 days to try it risk-free. If you're not sleeping better, moving easier, and feeling relief—full refund, no questions asked. You don't even return the device.
    How often do I need to use it ?
    20 minutes daily for best results. Most women use it in the morning while having coffee or in the evening while watching TV. It's hands-free so you can do other things.
    Is this just a heating pad ?
    No. Regular heating pads only warm the surface and go cold in 10 minutes. SiaaSoo delivers sustained therapeutic heat that penetrates deep into your shoulder capsule, plus built-in massage that physically breaks up scar tissue.
    Is it safe ?
    Yes. SiaaSoo is an FDA-registered medical device. The heat therapy is the same temperature used in clinical studies (40-75°C). If you have a pacemaker or are pregnant, consult your doctor first.
    Is it one-size-fits-all? Will it fit me ?
    It was designed to fit most adults comfortably, thanks to fully adjustable straps.
