My 18 year old just had the Synvisc One injection and her Dr. did the same thing. Walked in, started giving the shot (which was extremely painful hse says), then said, "ok - you're good to go", and walked out. She was in tears by the time we walked out of the office. It has been a week and she still has some pain and swelling. The day after we got home, we could see the lump of the gel sitting above her knee. I was kind of surprised that it wasn't injected under the knee cap but what do I know. This week it's not quite so bad but it's still swollen and painful. Is it normal where the Dr. put the injection? and the swelling?
