Does any of this apply?
Book an appointment
Arrange a routine appointment if you have repeated episodes of burning pain, warmth, and redness, particularly when they interfere with sleep, walking, work, or school.
Medical review is also important if symptoms are new, mainly affect one side, or began after starting a medicine.
