I have hard very painful sharp pain on the right side of my back, like right behind my ribs. it comes and goes almost in rhythm. If i lay in the bath it helps a lot. Im scared, I just stared a knew job today, there is no calling in sick, not sure what it is or what to do. This happened months ago, but it was both sides, and I was very ill with a fever, basically couldn t move, took some antibiotics from my dentist, that helped. (at the time I did not have health insure. but I do now. Just recently went to get a physical, every thing looked fine, mammogram and all, all though I have smoked for 12 years and was perscribedBupropion for a week then started the patches about a week ago. Really stressed about my new job, can t miss but have know idea how I can make it through. Its at Costco and very physical. I know you will say call your dr. just want to know if there is a simple explanation?
