Undiagnosed/Unexplained Burning Rectal Pain for 2 years

Digestive health

Hello, I am a 27 years old male. My pain started April 2018 (2 years ago). The pain comes when i have a bowel movement especially if my stools are a bit on the watery side. The pain is localised and is a an extreme burning pain that can last for hours after any BM. The pain started suddenly and i recall using glycerin suppositories due to constipation before the pain started. In the past two years I have done an MRI, MR Defecography( it showed a bit of paradoxical contractions), Anal manometry, colonoscopy, sigmoidoscopy and anoscopy and biopsies were taken. There is still no explanation. I saw an anorectal surgeon last year and he said I had fissures so I underwent a Lateral Internal Sphincterotomy. The pain only decreases a bit faster after the BM but its still bad. I went back to my anorectal surgeon and then he started speculating that I had Solitary Rectal Ulcer syndrome ( I have no rectal bleeding or mucus discharge) and he told me to do biofeedback which I did and had very little effect on me. He suggested Ulcer excision but I saw 3 other doctors that they saw no ulcer or anything else but just internal hemmorhoids. This has taken a mental toll on me as I live with this pain every day with no diagnosis. It is also worth noting that when ever I did enemas for colonoscopy preparations that salinity made my pain so intense that I had to take pain killers. As if pouring alcohol on a wound. I will attach a picture to point where the pain is (highlighted in green)

and I hope I can get an answer. Thanks

Could it be your haemorrhoids causing pain/burning? Has any doctor suggested that? Go back to your doctor for diagnosis. We can only advise here because we are not doctors.

Im so sorry for your pain. How aggrivating. Hang in there! Is there anything topically you could put on the spot that would soothe that area? Like petroleum jelly to where it would be protected when you have a bowel movement. You could try it and see if it would help. Maybe there’s something there that needs to heal? I’d get a syringe maybe or just apply it with a finger condom. Itd be a little bit of a pain applying it all the time but hey if it helped itd be worth it.
