Please do as much research and homework about the IOVER Treatment before considering having it done. I do not recommend this treatment! Today marks 7 days since I had the IOVER Treatment, and it did not provide any pain relief at all. The treatment was very painful, and my pain has increased since having it done. No pain relief at all! My knees are now more swollen and filled with fluid. I have been icing day and night, still taking a lot of Tylenol, elevating and taking it easy in hopes that it will all remedy with time and care. I had the treatment done in hopes to dodge knee replacement surgery. I know it has only been a week but was hoping for immediate pain relief as promised. I am doing my best to stay positive and hopeful for better results, but the last 7 days have been painfully frustrating. Please take care...sending warm hugs and much aloha.
