Excessive Sweat In the Anal and the Tail Bone end region

[Patient1010]

Dear Experts,

I am suffering from some serious symptoms:-

1. I got too much sweat on the tail end and anal region even in a AC room also. Even I am not getting any sweat from the rest of the body.

2. Sweat is more if i have an urge to pass the stool or urine.

Please let me know what may be the reasons for that?

I have the same problem. It started a week ago. Although it doesnt happen when i have to pee or pass stool. I also feel a burning sensation in my buttocks when i walk and before i know it my tailbone area is sweating like crazy. What could this be?

A common cause of excess sweating in this area can be human papilloma virus or hpv. Some strains infect the skin of the ano-genital region while others can infect the skin generally. The lower back can also be involved.

Hello,
This can be due to secondary hyperhidrosis skin and may be a part of an underlying condition like Hyperthyroidism or similar endocrine diseases and dermatological conditions like eczema, psoriasis.

I think getting a thyroid profile tested in the lab may help and also please consult a dermatologist to find out the confirmatory diagnosis as treatment depends on the same.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

Well over a year later, but I had similar symptoms one September at the age of 44.  I woke up one morning with painful urination, small amounts, and noticed sweating at the base of the tailbone region (upper buttocks), and especially so when I would have to urinate.  Later that day was able to see my OB/GYN doctor, (felt very much under the weather while walking to the clinic door) gave them a mid-stream urine sample, and it tested positive for bacteria.  I was put on antibiotics for seven days, as well as the a urinary tract analgesic called U.T.A, which helps reduce 'twitching' of the urinary tract, and so reduces pain.  I only used U.T.A. for one or more days as soon after starting antibiotic, the painful urination went away.

About 5 years later I had the same sweatiness over the tailbone region.  Next day, no sweating over tailbone region, but I had body aches and a low-grade fever of 100.  Felt like staying in bed much of day.  Like having the flu without the respiratory symptoms.  Anyway, the next day by afternoon, body aches again, and a sharp pain in abdomen area, especially when I got up from a laying down position or when I drank water. No painful urination, but was peeing often.  By that afternoon I had wiped myself after urinating and noticed brown streaks on toilet paper, just a few streaks.  I figured by then it was a urinary tract infection.  Next day went to the doctor, but was feeling a bit better (no body aches), but still had that cramping in central abdomen area, like a runner's cramp, which again would happen when I drank water or got up from a laying down position.  I made the mistake of drinking too much water before going to the doctor, and my urine was too dilute to test, so based on the symptoms, and after doctor palpated my organs in the abdominal area, including my kidneys, he noticed I flinched a bit when he pushed on my left kidney, so he figured maybe it is a kidney infection, but not sure.  He put my on Sulfameth/Trimethoprim 800/160 tablets for seven days.  Doing better, but still have that crampiness in abdomen.

Sweating in a certain region of the body other than the normal places, and especially if you haven't been exercising or working out in the heat, is a good indicator that there may be an infection going on in that region of the body.  At least, this is what I have observed in myself as I have never sweated over the upper buttocks before, so this was unusual.  So, don't ignore those localized sweat zones that happen for no known reason.
