bacterial infection
"I have a small either cyst or some type of mass on back of neck under skin. Doctor said it could be due to some type of staph. He prescribed me Bactrim aka as sulfameth.trimethoprim. He said two weeks to take this and if it does not go away we will need to Lance it. Which in a way I'm glad, it bothers me. Anyways I went to pharmacy to get my medicine and went home.  I actually started the same day taking my pill. Friday Saturday and Sunday I felt ok. But come Monday about 3 am I got up and had diarrhea, multiple times I felt nauseous & achey . 7 am I felt it in my throat I vomited  and after that I had a horrible headache. Can't eat, I feel as though my joints are stiff.  Doc is changing my meds. No sulpha again !"
