Internal anal lump , hard about pea size under the skin

Terrified is how I feel at the moment . My anus felt a bit sore after wiping , don't know why but felt around in cas if I'd "torn it " and felt a pea sized lump under the skin about 1cm inside sphincter. I've never had piles , no bleeding , not itching either. Feels movable like a cyst but joined on , not swollen like a pile , rubbery like a lipoma . No one available on the chat lines , surgery naturally closed over xmas , can't just talk to anyone , no support , nowt. I've emailed my surgery for a request for an appointment but after the xmas break I am now going out of my tiny mind with worry. I can't turn up at A and E can I? Especially with this covid explosion. I feel desperate I only found it this evening and cannot put it down to anything else other than cancer , it just does not resemble any descriptions of internal piles , can anyone please help ?
