I'm a 21 year old female. I have a very good diet and take vitamin supplements within limits. I have widespread muscle twitching all over my body with some muscle weakness on my left side. My limbs feel like they are burning, tingling, insects are crawling or biting me or even a sensation of water pouring on them for almost 3 months. But there is a certain peculiarity, I get twitching in my perineum area which is constant and unrelenting, it's very frustrating. I can't study, sleep or watch anything because my vaginal and rectal muscles are constantly twitching (painless) which is very distracting. I don't know what to do and I'm embarrassed to go to a doctor. Has anyone heard about something like this?
