Had my lst of three injections of Synvisc on april l8th in both knees. That night, had reaction in R knee. Swelling, pain, stiffness. Monday, had 40 cc s drained in R knee with a Cortisone shot By Tues, same thing happened. By Friday, went back to doctor. Had another 40 cc s drained in R knee. By Fri. night, both knees swelled, pain, stiffness. Went to E R (Urgent Care Facility) on Sat Morning. Had 40 cc s drained in R knee AND 20 cc s drained now in L knee. Swelling, pain, and stiffness by Sat night. Tomorrow, Tues morning have ANOTHER appt with doctor again. NOT having any more of the series of the 3 shots. How long is this going to happen before I find relief and get back to my original state before the first and only shot. Also, I was SUPPOSED to get Ortho Visc, and they shot in synvisc, did not know that until the shot was completed. If I would have known that, I would have not had it done, as I had synvisc about l0 years ago, with NO relief. The doctor said the ins. co. probably did not approve the Orthovisc.
