One Small Smooth Bump in my Anal Opening

Not sure what this is, but I have a small skin like smooth lump in my anus opening.
Sometimes its itchy and sometimes it burns…
Please help me just to identify what this is so that I can go to the right doctor or do the right treatment if its just a mild thing.
There’s no blood or rash or soreness… its just itching sometimes occasionally burn…
Please help me. Thank you. Very Much appreciated
