Thanks for sharing your concern.
Roughness in the lip could be due dryness,local application of moisturiser might help.
As your history suggests roughness and course mucosa of lip. then it could be due to local fungal infection
I would advise you to see your skin specialist for this as it is recurring in nature.
Meanwhile do not touch or rub it ,as it can lead to secondary infection.
Local application of moisturizer might help till you visit your specialist.
Hope this helps.
