I have a rash that appeared suddenly all over my body. it seems to appear in one location and then disappear only to appear on another part of my body. at first I thought it was an allergic reaction but it has now been 24 hours and is still appearing and disappearing.
Hello, You seem to have hives. I suggest you take an oral antihistamine e.g. Cetirizine tablet.  In addition, I suggest you apply a soothing lotion e.g. Calamine lotion to calm down the rash. Hope I have answered your query. Let me know if I can assist you further.
