Hello Dear,
Welcome to HCM.
Understanding your concern.
Thanks for your query . The symptoms you describe in your query Can be caused by various conditions ranging from simple
chapped lips to more serious condition like infection ,chronic allergy and auto immune disease like corhn's disease .
I would suggest you to to immediately stop licking and picking of your lips , because it will it away natural moisture of your lips and make then dry and swollen in long run, apply lip balm with SPF factor 15 ( sun burn can also cause dry and swollen lips), keep yourself hydrate by drinking plenty of water and start taking vitamine B2 and
niacin supplement .
If condition persist even after doing above treatment then
consult dermatologist and oral pathologist both for proper examination and to rule out conditions like
sarcoidosis and crohn's disease . Doctor may prescribe drugs like
isotretinoin ,antihistamine drug for allergy ,immuno suppressants or antifungal drug .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
