What Causes Swelling And Pressure Of Anus Radiating To Back And Hips?

Question : Hello I am XXXXXXX and I have had a problem for about 2 years. I had a weight lifting accident while doing squats and so I developed a varicocele which I had surgery for and is mainly fixed now. However, I also have pain and pressure in my back and also a full feeling in my anus. My lower back feels like there is a dip or indentation Like there is pressure or swelling. I also have a small hole above the anus. My anus feels swollen( especially after bowel movements) and has a pressure that radiates into my back and hips. It feels very sensitive as well and when I "flex" my penis it feels as though i cant and am only flexing my swollen anus. When engaged in sexual activity i have to use positions where i am standing and using my legs for support because the swelling causes my penis to become sensitive at the tip and causes spasm that lead to premature ejaculation. I really want help and am hoping i can finally fix this problem. In short I have lower back pains and a swollen and full feeling in my anus. I have looked into it and done research and it looks like it could be proctisis? Also sometimes it makes me have to urinate a lot in a small period of time or the sensation that I have to urinate.

massaging my back and buttocks helps a little bit it feels like everything gets a bit of relieve and isnt as tight and swollen but it only helps very little.
