I had a spinal fusion in Dec. of 2010, L5-S1. I was released from the hospital after five days, the surgeon said all went well. I stayed home and inactive for six week with the exception of walking and reaching one mile with in four weeks. I returned to work after six weeks, I have a desk job and do no lifting, ect. It is now March 17 and I still am having muscle spasms all the time. Is this normal and if so how much longer should I expect this to go on. The spasms are very uncomfortable.
