Can anyone shed some light on this. My left bottom eyelid has been twitching for over a week, I also have been getting for 6 years these weird feelings on my left cheek area, kinda feels like a spider web. I did have a brain MRI back in April 2006, everything was normal except extensive sinus thickening in the sphenoid sinus and lesser amounts in frontal area. I am at end wit, so scared, has anyone ever had this? What did you find out? My shoulder and neck hurts on the left side also, and also migraines (menstrual) in back of left side of head, Does a brain MRI show the brainstem? Please, if you have any thoughts or suggestions, let me know. Thank you kindly.
