I am a 57 year old ex pro skier who has had knee reconstructions (one from motorbike accident (medial lateral) and one from skiing (ACL plus torn achilles)), have run and gym almost daily for over 35 years. I have had a couple of arthroscopic cleanups on my knees over the decades and periods where I have been immobilised through knee pain and swelling. Haven’t ever used anti-inflamatories as I prefer just to work through it naturally. Last year I ruptured the miniscus in my left knee and have had a very painful recovery period lasting almost 12 months. A few weeks ago I came across Painmaster at a chemist next to my gym in CBD Sydney and I bought one. I have used it at nights for the past 2 weeks and while I am not running, I am training for 1 1/2 hours a day at the gym and amazingly I have no pain. It took a few days before I really noticed a big difference but 2 weeks on I am a total convert. The range of motion I now have is getting back to my athletic days and I am able to really push the leg strength training now. Brilliant find!!
