Cholinergic?: You may have what we call cholinergic urticaria which comes on after a rise in core body temperature . However if cold temperature causes it also then the probability of this condition is much lower even though cold-induced cholinergic urticaria has been reported. This condition is usually controlled by taking an antihistamine 1-2 hrs prior.
