In April I had two injections two weeks apart cervical pain etc. on my right side. The injections worked brilliantly however I began to have very similar symptoms on my left side so decided to try another pair of injections to see I could get the same results.
I had the first injection on the left and noticed that afterward I have had a lot of muscle twitching. These are not spasms, they are not painful. They are concentrated around the areas of pain (my arm, some in my neck and some down my back, one that even goes down my rib cage where there has been no pain). I didn't get great relief from the first left side shot and just had the second left side shot today. At this point I still have the twitching.
I've tried increasing my gabapentin to 600 at night, this has made no difference. I tried three days of valium thinking maybe the muscles just needed to relax but that also made no difference. I got a massage, just in case that might help (I have an excellent therapist). No dice. As I said, it doesn't hurt but it does seem to be related since it isn't all over my body, but just on my upper left torso, neck and arm. It isn't constant and it is mainly confined to one area or muscle at a time. It isn't bad enough that I, say, could't hold a full glass of water.
As I said the fasciculations are not painful but they are very noticeable. When I search the forums I mostly find posts about painful spasms and this seems totally different.
I'm curious if anyone else has experienced this after an injection? Or as a symptom of DDD or disc rupture?
