I was diagnosed with Costocondritis approx. 15 months ago. I sometimes have limited symptoms but the flare-ups are more than 50% time. Over the past few months I have done a but of research that leads to me believe I have Fibromyalgia- and have probably experienced the symptoms of Fibro for about 15 years. Ocer the last few weeks, I have been fighting some sort of sore throat virus/infection. A Web MD called in a Z Pak for me and I had horrible side effects the first 24 hours so they switched me to Amoxicillin. I npw have a white head rash on my chest, a yeast infection and my throat is now feeling as if there are little stones in there when I swallow. My voice is back, nasal drip is gone- but the left side of my throat is inflamed and irritated. I juat moved from out of state and trying to find a doc that is available. Any help in the meantime would be appreciated! 35 Female
