I feel I have to share this with you all as I am grateful my niece bought me a physical therapy kit for my knee pain and so far it has worked wonders. I always struggled in out-patient clinics because I never had the same person twice and always felt very rushed. It didn't work for me. This pack however, I showed to my current therapist and she said it would be very beneficial for me. It's quite simple but really does help. The website is called sohealth.co.uk and it was a knee OA kit. I have now purchased the hand one too!
