I have a itching/burning/prickling sensation whenever I start to do any activity like walk, jog (when the body heats up) removing the overcoat helps (I feel like rolling naked in ice),
But nowadays even at night while I am asleep and the heat in the room goes very hot, I have to get out in the cold for relief. Its very severe, esp on the upper body. The dermatologist gave me anti-histamines but nothing seems to work, he thinks I might need to go to a neurologist. Can someone help me?

Thank you

The prickly heat thing is often neurologic. I'd take the doctor's advice and see a neurologist.

More suggestions are welcome too
