I was diagnosed with tonsillitis on sunday and prescribed Penillcilin.

On saturday i had a soar throat and couldn't swollow this was when i started to be sick. By sunday morning i was in alot more agony with my throat and was still being sick so i went to the out of hours doctors. This was when i was prescribed pencillin.

Tuesday i went back to see my doctors, she agreed it was tonsillitus and advised me i must carry on taking my antibiotics. I told her i keep being sick but she didn't seem concerned.

I was sick again this morning but my throat is better i still have a little cough but not half as bad as it was. I have no idea why i keep being sick, the doctor doesn't seem concerned.

I can't be pregnant because i've just come of my period and 2 pregnancy tests say negative.

Any clues about what it could be?
