the hives are caused due to the release of the chemicals mast cells and other cells... this can be due to allergic or non-allergic... allergy can be to anything under the sun including the sun... this causes immediate erythema and itching and symptoms subside within 24 hrs in most and take a maximum of 6 weeks.. the non-allergic can be due to intravenous drugs and NSAIDs.. this type can also lead to severe oedema elsewhere and breathing difficulties..
