Have you talked to the neuro about this happening? While tingling can be a part of some simple partial seizures, it can be many other things also.
I am really concerned that you missed 4 days of dilantin last week....I guess it could be related to that or that would lower your threshold to have seizures too...
I would ask the doctor. When there are new things going on. (i do not have epilepsy, my kids do. I do have tingling in hands and occasionally legs from scoliosis, at time....)
it is aggravating.
I hope you get it figured out soon.
