Hi... Over the past two weeks I have had pain under my right rib cage. A dull aching pain that can be moderate to very moderate at times. The pain often migrates through to my back on the right side and up into my armpit/side of my right breast. I often have a gland in the left side of my neck that swells and is painful to touch. A couple of days ago I noticed a non itchy non painful slightly pink raised rash beginning on my right side of my torso. Today it has spread to May different patches up into my right armpit, under and beside my right breast and below my right breast. Last night I felt a painful lump for lack of a better word at the top of my right breast towards my right armpit. I have been going to the chiro as I originally thought the first pain was from a muscle issue due to my inadequate work station. However, given the new symptoms, I am not sure now. Any ideas what this may be?
