Symptoms of Anal Herpes
The symptoms of anal herpes are reasonably unique, but only if you know all of what you're looking for. If you're not paying attention, anal herpes can be mistaken for hemorrhoids, anal fissures, an allergic reaction, heat rash, a yeast infection, ingrown hair follicles, abrasions, jock itch or even insect bites. The reason these false diagnoses come up is because people are only paying attention to one or two symptoms instead of all of them.
The process of elimination by consideration of symptoms is called "differential diagnosis", and it's essential to dealing with the anorectal region.
So, in the interests of accurate diagnosis, all possible symptoms of anal herpes should be investigated.
Anal herpes, along with hemorrhoids and anal fissures, can cause a knife-like pain during bowel movements with the pain lasting for up to 15 minutes after the movement's complete. This pain is often described as "like passing glass."
Anal herpes can also leave bright red blood on the toilet paper, in the bowl or on the stool. It can even make you feel as though you have to pass a movement constantly.
When herpes manifests around the anus, it often forms a small crack or fissure instead of the more typical blisters, ulcers or rash. In a sense, it really is an anal fissure, just one with a viral cause instead of from overstraining.
You also may notice a bloody or mucus discharge.
The real symptoms that differentiate anal herpes from everything else are the specifics that identify an infection, such as swollen lymph nodes, fever, headache, muscle ache, burning sensation in infected area, lower back pain, and recurrence of symptoms. The infected area is usually painful and will probably itch, burn or tingle right before and during an active outbreak.
If that is true all I had/have are the blisters/bumps around the cavity... This is so confusing I hope this all clears up
