Hi Doctor, I have an arachnoid cyst. During the year 1999 I got some symptoms like dizzy and vomit. Neurologist said, there is a small water molecule in brain which called as arachnoid cyst and it is been there since I born. So had valparin200mg tablet for 5 years then I quit that as per doctors word with a checkup. During the year 2009. I underwent MRI scan as doctor wants to know the cyst status, then consulted the same neurologist for a regular checkup. Doctor said your cyst didn t grow, so it is in dead status, no need to worry. My question is, I used to drink beer very occasionally (monthly once or two month once, a bottle or two...since 2001)..last month I did night shift, during the period I got foot numbness feeling with some vertex pain. I consulted same doctor, he gave some neuro strengthen pills. Shall I drink beer occasionally, though i have some vertex pain? I used to smoke 2 or 3 cigarettes per day for past 5 years.
