<s>[INST] I was bitten by a stray cat last Thursday.  It swelled up and scabbed; some redness but went away.  I now have been having bouts of hives all over.  I also was wearing my moms clothes as i stayed at her house the weekend so maybe it could be the change in detergent?  I also am fighting off nausea. [/INST] Hello, Thank you for posting on Chat Doctor. The condition you have referred to is called Urticaria or hives. It's an allergic manifestation of skin, where an allergen leads to release of certain substances from your blood, leading to itchy skin rash and swelling over soft tissues. Its proper management requires thorough history, clinical and laboratory work-up. You may have to go for specific tests like patch test, food prick test, IGE antibody levels etc. As for treatment part, best would be the avoidance of allergen as far as possible. Try to eliminate possible triggering foods from diet. I would also advise you various antihistamines for long duration(at least 3 months) with or without oral corticosteroids. For non-responding cases there are many other Chat Doctor.  Hope this will help you in resolving your query. Thank you  </s>
