I recently had HA injections, not Synvisc, had Euflexxa 3 shots. Is it common to feel like a burning sensation all the time. Some relief during activity, but immediately afterward pain, burning pain and stiffness . I am 46 and have both knees scoped over 10 years ago for meniscus tears and tore my ACL 25 years ago and never got ift fixed which my ortho doc had x rays and thought I was in early stages of OA. I was not prepared for this, as my knees actually fell worse than the pain I had before. To all who have had these injections before, did you find the pain or feeling was different than before?It's been just 30 days since my first injection and 10 days since my last one. I am wondering that once this fluid wears off in 6-12 months, does the knee go back to how it use to be, or is the the body no longer capable of making it's own synvovial fluid?
