I am 16 and had 3 Synvisc shots at the beginning of the year in 2015 and I had very high hopes that the shots would help. I had a knee injury and they were supposed to make the pain go away. Everyone I know that have had the shots day they worked like a dream and were amazing. I did not have the same results. I still have the exact same amount of pain and what feels like a sore/painful spot where the shots were given. My first shot felt like a simple, nearly painless shot. The next two shots were given by a different doctor and hurt VERY badly. Is the sore spot normal almost 3 months later?
