question: A couple weeks ago I had what I thought was a stomach bug or food poisining a couple days later I developed swelling along my jaw and beside and below my ear with a red itchy rash and a mild fever. I went to the doctor and they did blood work for mono etc and a cbc all came back normal. A couple days later my joints in my left hand started hurting (never happened before) with some tingling. A few days later it all went away with just a little joint pain left. Now about a week later it happening again. The jaw and under ear nodes are all swollen and turning red and this time my ear lope has swelled up and turned beet red and the joint pain in my hand is getting bad again. Also the left side of my face appears to be swollen. I guess I need to go back to the doctor. What could be causing this?
