My Skin Starts Itching with rise in body temperature even very slight change in body temperature causes extreme itching for example Slight walking or Normal Workout and in Sunlight the condition gets Even Worse i can't even stand in Sunlight for more than 2 minutes Due to this i can't even go outside my home in daylight i am almost Trapped at Home for Past Few Months i have This Problem for Almost 4+ years now I Consulted many Doctors but Nothing Worked I Searched this problem on Google and found out that it may be "Cholinergic urticaria" or "Heat Rash" but the Problem is for both the above Condition the skin shows some Red coloured Hives but in my Case it doesn't So I can't conclude one more Guess is that maybe my sweat pores/glands are blocked so whenever my body temperature increases my body tries to sweat but due to blocked pores it can't sweat and the skin starts itching but that's only my guess If Any Doctor have experience in this type of condition please reply 🥺🙏
