It is amazing that all of you are open and helpful as I felt so alone in this you guys have made this easier knowing all this information you have shared. I was not given a choice on type of injection did not even know there was anything else. I have had three surgeries on the right leg with the rod to get to the point I could walk again. I was non walking for 5 months. The knee does not hurt if I lock it back and walk stiff legged not letting knee move if I walk normal it will have very sharp pains that will take my breath away. Carrying weight like buckets of water is painful no matter what I do.
