Hi Sir/Mam 1. I have been suffering skin red rashes whenever exposed outside 2 to 4  hours hot weather for the past 7 years. the rashes have disappeared in 3 to 4 hours. from past one year when exposed to cold and hot weather the same rashes are coming and disappearing. Now any climate rashes are coming when exposed to outside ( morning, afternoon and night). Even rashes are coming home but they are very mild. I am skin allergic(skin red rashes) to paracetamaul, painkillers, Antihistamines.. Medication: Am using homeopathy medicine from the  past 2 months as suggested by my local area doctor but rashes are still coming. lab report: Ace -120 esr-29 ige-245 frawns  grass and dust mite allergy. kindly suggest without antihistamine how to cure my problem.
