Recently, I've been diagnosed with mononucleosis. I had developed a rash on my whole body, but is slowly fading and you can now only barely see traces of it on my back and stomach. However, my arms and legs have started to ich relentlessly, but there is no evidence of rash or other problems. The itch is unbearable, and has ben preventing me from sleeping! We have tried almost everything, from different antihistamines, anti-itch lotions, and even oatmeal baths, but nothing seems to work. Does anyone have any idea what this is, or what I could do to relieve it?
