I ve been experiencing twitches for over three months. i m a healthy 20 year old girl but for some reason this is happening all over my body; my tounge, face, knees, feet, and my shin bones are starting to get this chilling sensation. ive been taking the necessary vitamins, my neurologist said the MRI of my brain is normal and she ran a blood test that looks good. but it s still happening and seems to be getting worse. I also stopped taking my birth control pills around the same time as when the twitches began, not sure if that s the problem. but i m worried as ever and don t want to think of the worst but can t help it!
