Cripple Tigger,
This is NOT NORMAL, and I wouldn't settle for staying on pain meds for 2 weeks from Synvisc injections. I had a terrible life-threatening reaction almost 2 yrs ago and had unbearable pain in my knee for a year...worse pain than prior to the injections. And my physician said it would just go away!!! Guess what? It did not.
If you are facing knee replacement, I encourage you to investigate ozone injections that are free of toxic chemicals and actually promote regeneration of the cartilage. Google ozone and prolozone, and Shallenberger to find a practioner in your area. That's the best advice I can give you, other than find a good natropath who does IV therapies such as chelation, etc to get this toxic stuff out of your system. Asyra Pro would help as well.
I feel your pain, as one orthopedic said to me, "I wish I had better news, but I stopped using the stuff early on because I didn't like the reactions I saw in my patients." He even said that he believed one of his patients went to a knee replacement sooner due to Synvisc.
Also goggle synvisc survivor blog to find out what you should have known before the injections.
YOU are NOT alone.
