hello, I had mastitis and I was given amoxiline which has penicillin in it. I took them for 3 days . on the second day I started having diarrhea, vomiting, and bad stomach pain and I feel dizzy most of the time. I almost fainted many times. now I was given cyclizine tablets, I took one and my sickness went away . apparently I started feeling some pain in neck when I checked in the mirror I saw that my tongue colour is really changed to very white colour and my head is burning. please doctor answer me I am really worried.
