Hi, I am 35 years old female. For last 1 month or so, I have been constantly having hives with lot of itching on my thighs and legs. I take cetrizine or Allegra 120, after which they disappear. Earlier, I was having them after 2 days, but now I am having it every day. It could be due to dry skin in cold weather, because of which I try to moisturize it every day, but not of much help. I am not sure, what are the triggers causing this allergy, though I am asthmatic, because of which I take Budamate inhaler every day. I hope taking allegra everyday is not harming me, or can you please advise any alternate treatment which helps me permanently.
