Treatment For Swollen And Tender Buttocks, Constipation, And Piles?

I really hope this site is genuine, I am in absolute agony. The bottom of my left bum cheek is slightly swollen n is very tender and it spreads over to my perineum. It is rock hard and very painful, during bowel movement yesterday I applied pressure to this area and it seemed to ease it, I suffer with constipation and as a result piles, my parner just thinks that it's my piles that have flared up really bad, I'm concerned as I think he is wrong I think that there is poo caught there which is why I have the pain and tenderness, I have been using treatments for piles ie suppositories and cream and it's not helping, I have also been taking ibuprofen to help ease the pain but I am having no luck. This has been like this since Tuesday early evening. Please help me, tell me what to do I have never felt pain like this and have gone through two labours without drugs, so as you can tell my pain threshold is quite high. Thank you
