Hello Welcome! I would be pleased to answer your question . From what you have described in your history , it looks very much like acute papular urticaria . most episodes of acute urticaria are self limited within 4-6 weeks of onset of symptoms, it is not imperative to do so. I would recommend taking an anti histamine once or twice a day for 2 weeks + calamine lotion over the affected areas whenever symptoms occur and seeing whether they recur on stopping the medicine after 2 weeks. If they do then restart treatment for another four weeks and then stop and see. If they still recur then you will require some blood tests and will need to see a doctor in person. Please note that if you have any lip swelling or difficulty in breathing you should see doctor right away. Hope this information is useful, please feel free to ask if you have any queries.
