Hi Doctors, my left eye is twitching randomly many times in a day since last 25 days. I have a history of low b12 and vitamin D and 2 year back at the time of delivery doctor prescribed me supracal K and vitamin 12 medicine. Which I started taking again and noticed that my eye flickering got less... But it's still there and thats irritating me... Also I have severe left shoulder and neck pain since last 3 months... When I visited doctor for that he gave me vitamin tabs and pain relief tabs which are not helping me to resolve the root cause of it. He told me to not ride bike, which I stopped but my shoulder pain still increases time to time and now every morning my left side neck is becoming stiff and painful... Please help me...
