I Have Had Strep Throat And Was Taking Antibiotics- Which

I have had strep throat and was taking antibiotics- which then gave me a yeast infection. I went to my doctor and the BV and yeast test came back positive. The medicine they gave me on Last Monday has made me very sick- all of the side effects that say call your doctor right away. I called- she got back with me and said the they had to cure the infection and I had to just deal with the side effects. I took the medicine and dealt with the horrible side effects. I have been throwing up now for 7 days. I can only keep water and yogurt down. This morning I woke up covered in a rash all over my body- it itches. I called back and they told me to keep taking it! I feel much worst now! No fever!
