About 6 months ago the skin around my mouth starting burning, turning red, tingling, swelling. At the time that this started the effected area was small. Now, however all the skin around my mouth is now red, burning, etc. The swelling, redness, etc last for 2-3 days and will go away for 2-3 days and then it starts all over again. I don't know what to do, please help.
