Severe rectal inflammation from a UC flare can make it feel like you are crapping out razor blades, but that sensation only lasts while pooping. No pain sitting, or touching that area (like when wiping with tp). If you have a UC flare then you know the rest of the sensations of severe rectal inflammation: tenesmus, bleeding, frequent bms, and may/not include blood. You're not just going to poop out razor blades, it would come with the rest of the awful symptoms too.
A fissure's pain persists after you are done pooping, which can be short or long. However that pain will subside before the next bm. A fissure can have a terrible smell, and might expel puss. A fissure is going to be painful and you might feel pain when sitting or touching that area. I'd say the persisting after a bm, and pain in touching that area with TP would be good indicators that you have one.
Anal fissures are cracks or tears in the anus and anal canal. The primary symptom of anal fissures is pain during and following bowel movements. Other symptoms that may occur are bleeding, itching, and a malodorous (smelling very unpleasant from pus) discharge.
Squatting over a mirror (or having a spouse look) might help. Anal fissures are diagnosed and evaluated by visual inspection of the anus and anal canal. Gentle inspection of the anus can confirm the presence of a fissure. If gentle eversion (pulling apart) the edges of the anus by separating the buttocks does not reveal a fissure, a more vigorous examination following the application of a topical anesthetic to the anus and anal canal may be necessary (via a doctor). A cotton-tipped swab may be inserted into the anus to gently localize the source of the pain. An acute anal fissure looks like a linear tear. They look like a red paper cut, it would be very near your sphincter (at the edge or just within). /www.medicinenet.com/anal_fissure/article.htm
We can also get perianal abscesses
, they look like red pimples very close to the sphincter. They can burst as well and cause pain, release puss and blood.
A fissure or abscess benefits from Sitz baths. Sitz baths (essentially soaking in a tub of warm water). Sitz baths are encouraged, particularly after bowel movements, to relax the spasm, to increase the flow of blood to the anus, and to clean the anus without rubbing the irritated anoderm.
