This patient complained to me that she gets rashes when she comes walking to the clinic in the morning. Today she showed me the lesions, numerous small (1-4 mm in diameter) pruritic wheals with surrounding flares. Lesions used to subside in 30 minutes. A diagnosis of cholinergic urticaria was made.
