HI, THANK YOU!  GLAD UR HERE CAUSE THIS IS EMBRASSASING!  HAVE PAD AN JUS RESENTLY I NOTICE MY SKIN ON INSIDE OF CHEEKS IS VERY BLACK SEEMS TO BE THICKER THAN NORMAL AND LOOK CRACKED IN SOME AREAS,, ALTHOUGH ITS NOT HURTING ME IN ANY WAY// TRYIN TO FIND A ANSWER BEFORE GOING TO DOCTOR IF NOT NEEDED
Thanks for your query, I have gone through your query. The black color of the mucosa or inner aspect of the cheek could be a normal physiological pigmentation or increased pigmentation because of chronic irritation because of smoking. The thicker mucosa could be because of frictional keratitis or leukoplakia or niche plans or candidiasis. Consult an oral physician get the above said conditions ruled out. If it is frictional keratitis, remove the cause like sharp teeth by rounding off the sharp edges. If it is candidiasis then you have to take topical antifungal like candid mouth paint. If it is leukoplakia, you have to stop the habit of smoking and take antioxidants like capsule lycopene. If it is lichen plans then you have to take topical steroids like triamcinolone acetone (0.1%) 4-5times daily for 1 week. I hope my answer will help you, take care.
