Hello doctor, Since past 7+ days, I've got some red patches throughout my body, mainly on hands, legs and stomach area. When I searched on the internet, I think it's probably urticaria. It looks like red patches with some white rashes sort of inside those red patches. I've took Allegra medicine for 3 days (1 tablet each day) and I observed that I could see some benefit like the patches became ligher and dried actually. PLEASE TELL ME IF I'M TAKING THE RIGHT MEDICINE. WHAT SHOULD BE THE DOSE FOR EACH DAY? AND FOR HOW MANY DAYS? Because today I didn't take the Allegra medicine and I observe that more smaller red patches are appearing. So, should I continue taking the medicine for effect? ALSO, WILL DERMOCALM LOTION HELP? OR PLEASE PRESCRIBE ANOTHER TREATMENT. I hope you'll help me out and suggest the right treatment/medicines. I've added photos.
