I'm a 22 year-old male who has been suffering from rectal discomfort for the past 7 years, to the extent that it has greatly impacted my quality of life.
How it got started: I used to have a pretty bad habit of using perhaps excessive force when wiping. I'm right-handed, so naturally this meant that the left side of my rectum often bore the brunt of my forceful wiping techniques. The details are a little hazy, but from what I remember, one day, I wiped too hard and felt as though something on the left side of the anus had snapped or popped, or perhaps had become displaced. Ever since then, the left side of my anus has been uncomfortable. I should note that this happened at a time when I was suffering from quite a bit of anxiety, which was probably a contributing factor.
Symptoms: The discomfort seems to vary in its quality and severity, but is always located on the left side of my anus. At times, it will feel as though something is missing, as though the skin on the left side of the anus was lose or untethered, or simply abrasive/raw/irritating. There can also be a sense of topographical unevenness with respect to the right side of the anus (which has never caused me any problems, event though my physical therapists have told me that it is also tight). It feels like an infection, but antibiotics have done nothing to alleviate the discomfort and I can pinpoint a clear physical event at which it began, so I doubt it really is one. I will also sometimes feel movement on the left side of the rectum, which might be muscle spasms. I have seen a physical therapist, who told me that the muscles on the left side of the anus were tense and curled up.
I do feel occasional relief after urination. The feeling is that of fluid being retained and somehow pushing or swelling against the muscles. This relief vanishes when the fluid is pushed out (by say, sitting down).
I have seen a urologist who prescribed antibiotics for prostatitis, but they offered no relief to my discomfort. I have also attempted physical therapy, to no avail.
Any idea on what this could be or how I can solve it?
