Hi dr i somehow unbeknown to me bruised my index finger the line (fold) closets to my nail. its is really bruised not painful but sensitive i have taken photos?

It is not feasible to provide a meaningful opinion without additional history, and physical examination. If the lesion is getting better, you may watch and wait. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV and Covid vaccines.

Photo is helpful. Normal bruise should resolve by a week or two. If it persists then you should check with your primary care. I am making a guess that you are not on any blood thinner or have neuropathy that you did not notice any injury
