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.
