Hi. First time using anything like this

i have a small pea size lump just outside my anus. The lump is painless and hard. At first i thought it might be a spot, on occasion I get them and they pass and normally are painful to touch and squeeze. This is different though and stayed the same size for 2-3 week.

not consulted my gp, yet. Have tried anusol cream and whilst I think it could have reduced, today it just feels the same size as a few weeks ago.

in terms of any other symptoms, I noticed some bright red blood on tissue after a number 2 but was extremely minimal, hence seeking the anusol cream. The lump doesn't inch and from what I can see isn't a different colour, just a bit red 

any advice appreciated, thanks
