The reason why we have a butt, is because in that but is the largest single muscle that we have in our body, it actually contains three muscles, the gludius maximus, gludius minimus, and something like the gludius medius. but all in all, we are the only animals that stand up right, and we need that extra muscle there to get up and keep ourselves up, without them, standing up would be a very strenuous and almost impossible task

The crack of my butt -- high almost to where it ends near my lower back is scaly and red and itchy and when I sit on the toilet it leaves a pink blood stain -- not a lot but it s raw enough to slightly bleed but not hurt. In and around my actual anus it is very itchy and has been for years. I try cortisone creams live Walgreens etc but the cream itself makes the condition worse. Prescription strength corticosteroid make it go away and I have even gone so far as to spray the area with flonase nasal spray my mother used for her allergies but I noticed that after I did that I got stretch marks on my lower belly which are now going away. The folds between my buttocks cheeks are now left to right brown/red stained or strangely pigmented mirror images of each other. The texture of the skin is otherwise normal with no skin tags or warts . The area directly around my anus is flaky and itchy and I can peel it off like onion skin. I am a male 46. I have gained a lot of weight slowly over the past 8 years ( about 50 pounds) and I am under psychiatric care for panic and anxiety but in reality I can t climb stairs or walk fast because I get light headed -- this is not panic -- I just assume it is because I am too afraid to let an MD touch me unless its to see a psychiatrist -- I am now taking 4mg alprazoloam per day and mg Inderal. Sometimes the symptoms are better but overall I am severely agoraphobic and my life is awful -- I do not feel like a normal person and it s not mental. I work as a writer and I write very well but my mind is very screwed up. I scare easily and things that would normally just annoy someone, make me get very weak where I have to lie down and sleep -- when I can sleep -- if I am out in the sun or I get hot I feel awful and if my shower is too warm I take hours and hours to cool off. I also have wheezing when I get nervous -- like taking a shower. The wheezing is not that bad but I can feel it. I cannot lift or carry anything -- I get so weak so fast that I have to lie down and rest -- sometimes it takes days to get over this. This atrted in 2006 with a full blown panic attack and some kind of subsequent nervous breakdown but prior to that I was fearful of cold sores which wi Oulw get once every two years -- most of this started after the death of my younger brother which was very bad but I find it hard to believe that everyone else in my family is okay, but I am this big fat, sweaty, out of breath, itchy assed, guy who can no longer work or do anything sociable without having a glass of wine -- if I try to take less xanax I get horrible withdrawal symptoms -- all it does not is keep me from getting withdrawal -- there is really no ther purpose for taking it.. Also, this all started at the same time I developed a lot of discreet keratosis on the backs of my hands and the tops of my feet.

my husband just informed me that his butt crack is raw and is starting to itch possibly from trying to heal but within the last 2 days he has experienced bloody stools and blood on tissue paper. I am really worried. I know he has alot of stomach problems such as ulcers. What could be the cause of his symptoms? He is 43 years old

The area around my butt crack is irritated and has been for some time. It is itchy and if I scratch it, it will peel. Usually it will then get harder bumps like a bug bite will over the area that peeled. Then it will lightly scab over which will then peel again. Then it might repeat the process or go away for a week or more and do it again. What is this?
