Labial artery prominent? Of infection?

So i have a recent history of getting my bucval/labial mucosa dry,pigmented and keratised(roughness). Also i have noticed in my right buccal mucosa near to the buccal floor and on the lips, the artery got more prominent where the pigmentation has occurred, is it a sign of infection? I am sure few days back when this pigmentation had not started in my labial mucosa this artery wasn't felt that time but now it is! Please guide me. Also when i blow air in my right buccal mucosa sometime i feel a filling of air like think near my tmj lik when u do valsalva with nose and you ear drums expand and collapse, similar, also a little pain was there along the jawline bone just below ear and near tmj. M scared, please guide me.
