Hello, In October I had brain surgery to remove a lesion on my right frontal lobe. The pathology results of the lesion were somewhat inconclusive and basically suggest a demylinating process. Prior to the surgery I was having seizures and that is how the lesion was found. I was put on Keppra 1000mg daily, after the surgery. I have since gone down to 500mg daily and about 3 weeks after the surgery I began to have what I thought were muscle twitches on my left side. They have since spread to my right side as well as my left side and include the arms, legs, and feet. Could these be myoclonic or do you think they are a side effect of the medication (the twitching does decrease right around the time I take the Keppra)? Does anyone else experience these twitches? Some of them are really small, but a lot of them are very noticeable and annoying.
