[|Human|] This health issue relates to my father whose age is 63 and wt. 90 Kg. In last one month every day a swelling develops in some part of his body. It started with  his hands and initial thought was it could be infection as he had small cut and so he could have been infected. Accordingly he was treated with antibiotics but later the symptom (swelling) moved from hand to other parts of body. He was prescribed course of anti allergens for a period of 3 weeks. It has subsided the intensity of swelling but it is still there. Every day either swelling will move to a new area or existing one will increase in size.Please advise.Thanks,Prateek
[|AI|]  Hi, it appears to be the allergic reaction, called urticaria, may be due to the allergen he is using daily, main thing of the treatment lies in detection the allergy causing substance and avoiding it.  Avoid using the things one by one and observe, when ever the swelling is minimal note that substance and avoid it forever. Like this if you avoid the things in foods, oils, cosmetics, etc. you may get complete relief. Thank you.
