<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been experiencing involuntary contractions of my eyelids. My eyes blink frequently and sometimes they remain closed for a longer than usual duration. Is this something I should worry about?  <response>: It sounds like you might be suffering from blepharospasm. The best medication for it is Botulinum Toxin Type A Botox.
