I was given methylpred 4mg yesterday, took all of the first day. and have taken todays, except for bedtime. My eyes are burning, my nose is running non stop, cramps accompanied with diarhea. I feel like I am on fire. I cant eat. it makes me very nauseated. and to drink is very difficult. I feel full. What is happening to me. I was diagonosed with pneumonia in my left lung. Also given Amox/k875mg. , attusshx for pain, I have only taken one of these attusshx. I have a very low tolerance to medicine but this is scarey. Please tell me if I should stop?????????????????
