Hey my name is Rebecca Marini, I am 25 I went to the hospital last weekend with severe abdominal cramps they did an ultrasound and everything was normal. But they did find a UTI so they sent me home with some Bactrim to clear it up. My problem is its the end of the treatment and 2 days ago I developed a fever, chills, still having cramping in abdomen and lower back, my face is really flushed and I develped rashes in various parts of my body. Is this normal or should I be seeking more medical care?
