I had a very bad case of cellulitis in both calves two weeks ago. After finally getting the right combo of antibiotics from my primary care doc (the ER prescribed something that was ineffective), it went away. On Thursday I noticed a few red welts on both calves, very itchy and sore to the touch (firm under the skin). My calves ache. On Friday, the number of welts had doubled. I sent a photo to my primary care doc, she said it looked like hives and told me to take Zyrtec and Zantac and to monitor them. After some online searching, chronic hives seems to be a symptom of some people with auto immune disorders. Has anyone on here experienced this? Beyond my hematologist, is there a specialist I should consult? I have had excellent medical care for the record. Having one of my first really down days, I've been fortunate to lead a fairly normal life from day to day despite my numerous, hefty diagnoses.
