For 2 weeks I have experienced a "shaking" inside from what I think is from an S1 nerve block. I don't have any type of shakes with hands or anywhere else, just inside. Two weeks ago I had this nerve block done for my left leg. Thursday the 18th (tomorrow) I'm going in to have my right leg done. I have been taking the generic of Neurotin (Gabapentin) for the nerve pain. My amount I'm taking is 2400+mg's a day. My question is, does the steroids from the injections have the effect of internal "shakes" for 2 weeks or more? With taking the Gabapentin everyday, I'm sleeping 5 to 6 hours a night. I tend to think if I didn't have the Gabapentin I would possibly sleep 3 to 4 hours a night. Anyone experience this? If you feel I have not explained enough, please ask me questions.
