I am on my second month of teriparatide injections.For the first month I was experiencing no trouble at all but now I get severe back pain. If we go out for the day I feel fine walking with the aid of a walking stick or crutches but after about twenty minutes the pain starts and sitting and resting doesn’t alleviate it at all.Is this a usual side effect and does it ease after a while or do I need to stop the teriparatide injections?
