I was biten by an insect, treated by a 5 day antibiotic bc of the fever, swelling and pain, 2 weeks later all of my joints swelled, with achiness I felt that I had a bad fever, after much test was diagnosed with fibromyalgia, and now sjogrens? Never hade any problems until insect bite...could insect bite have resulted in my present condition of fibromyalgia and sjogrens?
