This is a long description of what is happening - strange. I have itching on my skin, maybe beneath my skin, since it doesn't show on the surface. Its like the itching that you have when you react to "quinine" - hope you know how that feels. This itching only happens as a result of temperature change in my body and it continues for minutes (5,10, 20.. depending on how quick my body temperature stabilize). Now I think its more connected to coldness in my feet as the heat withdraws to the other part of my body. When the temperature increases sharply, then my body reacts, same when the temperature drops of sudden. It happens almost every day when i take my shower, after coming out of the shower and my body temperature changes. I can no longer bath with cold water at any kind of temperature. I have lived in both temperate and tropical region and the situation remains the same. I have tried several creams, soap, changed my towel and did skin test. Well, no result shows the reason why. One doctor told me its some thing like "neuro-thermal allergy". I am still looking for what that means. There was a time I had to stop taking Milk, because I had the reaction for a long time and my skin started having some rashes from excessive itching. Well, I never confirm if this is actually the cause, but it worked for some times... only for the itching to continue. Ha, I remember, when I walk or run and I sweat, then the itching starts.... its mostly on my back, upper arm, thigh, some times chest, leg... My neck, face and hand are safe :D. What could this be? if there is need that I explain more, because many doctors don't have time to listen to long stories, that is why I am turning to the internet for answer.
