eyelids and people damage

hosdel

Dear friends

I am from Sweden, I had 6th operation (Medullary thyroid cancer)about one month ago, unfortunately after operation I got infection in my blood during surgery, lot of pain in my stomach, I was using pain killers like morfin for more than 2 weeks.
after operation I found one of my eyelids ( left side) is fell down and makes my eye smaller than other, moreover right people of eye is three times bigger than another.
I didnot had even small problem in my eyes, but now I dont know what is happened to me.
I referred to eyes Dr. but he said I cannot the nerves has damaged or cut.
if anybody had such experience please tell me how much time will i need to get back if my nerves damaged?

Best Regards
