I get 1red itchy bump that last only 2 ~3 hours lower abdomen two weeks before menstrual cycle?

Exam: Skin lesions need to be seen to get a better idea of what it looks like. If it only last a couple of hours it is going to be hard to time an in person visit. The next time it appears log in to Healthtap and schedule a virtual visit. One of the primary care doctor or Dermatologist can visualize the lesion and help determine the proper evaluation
