New to this

Hi everyone.
As its my first post I'll introduce myself.
My names Ryan, 22 from the UK (south east)

So for my reason on posting...
About a week ago I started to experience pain above my anus crack and felt a slight lump. Was uncomfortable but noting major. As the days went on it got a lot worse and last Saturday a hole appeared and pus started to SLOWLY weep. Not burst just weep from this hole.
Yesterday I went to the Dr as the pain was unbareable and was given Fluxxacilling 500mg (SP?) also told it was a polo nodal sinus and told if it gets worse to go to A&E within 24 hours.

Anyway I awoke today with pain I can only desrcibe as having a dagger in my anus while a donkey kicked the area. I took a bath and carried on with the compress as usual but no relief. Upon inspection I noticed there was a 2nd large lump that looked full of pus. I caught it with my flannel washing and even though I am a man I nearly hit the ceiling and cried after grazing it as its the most sore anything has ever felt.

Fast forward an hour and I've decided to go to A&E, getting ready to go and say on the sofa before I went. Went to stand up and no pain. I quickly realised this new lump had burst and this one really had burst, huge amounts of pus down my crack and all down my leg.

As of right now I'm in no pain just sore, do my question is do you think it was really a pilonidal sinus or just a cyst/boil? Should I still go to A&E?

(PS avoiding hospital as my mum died in ICU last year and can't face it without good reason) and obviously as I said pain free?

Thanks for reading
It sounds very much like a pilonidal abscess, caused by a pilonidal cyst becoming infected. Best to go back to GP. The antibiotics will deal will the infection and you may now be lucky and not have a recurrence, however many people do get repeated 'flare ups'.
