2 years ago hives started on my arms legs and belly. Steroid was prescribed and they cleared. Current, have probably 30 plus bites/hives on stomach, legs and arms. The bumps on legs are very itchy and at one point were large and filled with pus (round welts). I have checked my home/cats and have not changed my diet/laundry detergent, etc. One doctor thinks it is stress related, the other - bites? This has been occurring going on 2.5 months. The ones on my legs that were fluid filled at one point have yet to heal - been over 2 weeks and they are just a round, flat and red. Prescribed hydroxyzine and a cream to put on bid...nothing has helped. Not sure where to go from here?
