Labial artery swelling? Is there?

Why is this labial artery swelling is there? First pigmentation started then little inflammation then this artery was prominent. Same in buccal mucosa, all the dentist and ora pathologists said its not OLP, but dermatologists are saying its OLp, i have no symptoms apart from dry mouth, only once or twice i felt burning/stinging at this labial mucosa, i dont have any bad habits as well as this condition started after taking covaxin! I have already used kenacort, rebagen, lycostar, becosule z and caziq as well, TC creams do reduce it for a while but later it increases. Even I showed on ent locally he said its normal melanosis, My buccal mucosa feel like keratosis, rough. And mainly in right buccal mucosa floor also i can sense an artery, i am worried, please help me! I am worried about cancer. M just 24 without any bad habits :(. Sometimes dry tongue and mouth, nothing else.. I have high ige 440+. Please help me, i am really scared :(
