Cpla upper lips? This vascular anomaly?

So after covaxin, nt sure due to vaccine or something, i have this artery felt prominent in the upper lip, its kind of U/C shaped, i had showed it to dentist but he said nothing to worry about, i had post inflammatory pigmentation as well in my buccal mucosa which my dentist said its oral Lichenoid reaction which will subside, probably triggered due to vaccine, for sample pigmentation see my lower lip, there's a brownish macule, i am taking homeopathy and the oral mucosa has healed really well. My current problem is, in my upper lip, at the middle of the lip at the tip(or maybe termed as vermilion border), very small whitish colour ulcer forms usually, and m sure I don't bite that place.. my question, how to cure this vascular anomaly? It creates stinging sensation sometimes and when i use flashlight there's some ulcer type thing, very small but yes whitish.. help me.
