Rash in butt crack - Men's Health Message Board

My CrossFit journey was still in its infancy when I became acquainted with monkey butt MB. MB is not unlike food poisoning, sneaking up on you uninvited and.

I recently discovered a rash at the top of my butt crackright between the cheeks.  I don t know how to explain it, but it looks like i have burns down there.  It s all red and irritated and there are a couple patches between my cheeks that look like permanent scars or something. Literally, the surface of these sores look like scar tissue after a burn.  But they don t feel like they burn.  I have noticed that they become pretty moisteven after i shower and dry myself about ten minutes later the rash/burns/scars are moist againwith a very light odour. It sometimes itches but very rarely, and it doesn t hurt to pee or anything.  I am sexually active, but i have only been with one man and he is cleanso i don t think it is an STI or STD or anything. I shower and keep myself clean every day, but i have no idea what it is.  Could it be from my butt cheeks rubbing together or something.  I m pretty worried but i don t want to see a doctor.  Does anyone know what this irritated burn-like rash/scarring could be, and what i could use to cure it.

Hi,

There could be several causes for the symptoms you are having. You should reconsult with your doctor to rule out the following possible causes -

Perfumes, chemicals, or dye on toilet paper can cause an allergic reaction.

Moisture from sweat or diarrhea may cause itching. If the anal skin stays wet, the skin begins to break down.

Some foods irritate the anus when they are expelled during a bowel movement. The most common culprits are caffeine, chocolate, beer, nuts, dairy products, and spicy food.

Infections such as pinworms, yeast, and genital warts can cause itching.

Hemorrhoids, which cause painful swelling of blood vessels in the anal area, can cause itching.

Cancer, in rare instances, may be a cause.

Therte are certain factors which predispose to the risk of developing anal itching as a symptom.

Factors that put people most at risk for anal itching are as follows:

Diabetes

Recent antibiotic use

Chronic dry skin conditions such as psoriasis and seborrhea

Profuse sweating.

Do discuss these with your doctor and exclude any possible causes in your case.

Post us if you need any further information and let us know about how you are doing.

Regards.

Ive got a butt burn too it hurts like How can i get rid of it Ive had a little Diarrhea today

use baby diaper rash cream because i had that exact thing happen to me

Check and see if you have hemorrhoids.  if you have hemorrhoids your body can create moisture or leak moisture that can create a yeast infection or fungus to grow in the area.  Treat the hemorrhoids and then you can win against the yeast.

Based on the location, you should also be checked for the possibility of a pilonidal cyst.  They always occur in the area of the coccyx.  The rash may be a breakdown of the skin due to something such as an ingrown hair. Do have a doctor check it out.

Rash in butt crack

I have been dealing with this rash in the crack of my butt for several years now.

I thought it wasn t that bad appearance wise, but after my girlfriend commented on it the other day I looked at it and it was VERY red.

Basically, I have a very red rash that is only inside the crack of my butt where the skin touches. It runs from the back of my perineum to the top of my crack and in around that whole area. Both it and my anus itch, sometimes not at all for almost a whole day, sometimes enough that it about drives me nuts, and most of the time somewhere in between.

The itch has been there for a long time in that whole general area but the rash was not this red last time I bothered to look at it which was probably months ago.

For whatever reason I suffer from profuse perspiration in that area and on my butt cheeks themselves. I ll get perspiration there even when I m sitting in a chair, and it s way worse if I m actually doing physical activity enough to soak through my pants. It s embarrassing, I think it may be the cause of this rash, and when there is a lot of it down there I think it aggravates everything and causes it to itch more. The skin in that area always feels moist and it often feels like I am scraping off dead skin with my fingernails when I itch.

I really don t know what to do with this thing, and I m really embarrassed about the possibility of seeing a doctor about it.

I know this is probably going to get lots of jokey replies but here goes, it s a serious problem. Basically, I have been working over summer in what is.

A MAX232 chip

The die of a MAX232

The MAX232 is an IC, first created in 1987 by Maxim Integrated Products, that converts signals from an RS-232 serial port to signals suitable for use in TTL compatible digital logic circuits. The MAX232 is a dual driver/receiver and typically converts the RX, TX, CTS and RTS signals.

The drivers provide RS-232 voltage level outputs approx.  7.5 V from a single  5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to  5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.

The receivers reduce RS-232 inputs which may be as high as  25 V, to standard 5 V TTL levels. These receivers have a typical threshold of 1.3 V, and a typical hysteresis of 0.5 V.

Versions edit

The later MAX232A is backwards compatible with the original MAX232 but may operate at higher baud rates and can use smaller external capacitors – 0.1 μF in place of the 1.0 μF capacitors used with the original device. 1 The newer MAX3232 is also backwards compatible, but operates at a broader voltage range, from 3 to 5.5 V. 2

Pin-to-pin compatible versions from other manufacturers are ICL232, SP232, ST232, ADM232 and HIN232. Texas Instruments makes compatible chips, using MAX232 as the part number.

Voltage levels edit

It is helpful to understand what occurs to the voltage levels. When a MAX232 IC receives a TTL level to convert, it changes a TTL logic 0 to between 3 and 15 V, and changes TTL logic 1 to between -3 to -15 V, and vice versa for converting from RS232 to TTL. This can be confusing when you realize that the RS232 data transmission voltages at a certain logic state are opposite from the RS232 control line voltages at the same logic state. To clarify the matter, see the table below. For more information, see RS-232 voltage levels.

Applications edit

RS-232-to-TTL converters that use MAX232

The MAX232 A has two receivers that convert from RS-232 to TTL voltage levels, and two drivers that convert from TTL logic to RS-232 voltage levels. As a result, only two out of all RS-232 signals can be converted in each direction. Typically, the first driver/receiver pair of the MAX232 is used for TX and RX signals, and the second one for CTS and RTS signals.

There are not enough drivers/receivers in the MAX232 to also connect the DTR, DSR, and DCD signals. Usually, these signals can be omitted when, for example, communicating with a PC s serial interface. If the DTE really requires these signals, either a second MAX232 is needed, or some other IC from the MAX232 family can be used. Also, it is possible to connect DTR DE-9 pin 4 directly to DSR DE-9 pin 6 without going through any circuitry, which provides an automatic brain-dead DSR acknowledgment of the incoming DTR signal.
