What is happening to your skin when you have an itch?

I have heard several different explanations. Some are more scientific than others. It used to be that some doctors thought itching was actually a slight form of pain, but this is not believed to be the case by most folks today. \nSome believe that irritants landing on the skin cause itching, but itching can also be caused by skin stretching too quickly (which often happens during pregnancy) or is too dry. \nSome people think to remedy skin itching taking zinc or using lotions will ease the symptoms. Others suggest running cold water on itches or hot water on itches. I have also heard of people alternating super hot water to kill the initial itch, and follow it quickly with colder water. Doctors tend to discourage use of hot water, as it dries the skin further and since lack of moisture is one reason to have itching, keeps a vicious cycle going.\nBut all of this does not generally answer what an itch is. Most medical definitions are not helpful in that respect, and it was years before I got any sort of real illumination on this issue. It wasn’t till I took zoology and genetics that one of my professors finally made it clearer.\n I was lead to believe by my professor that it was really mostly a case of a sodium build up around the mylination around your nerves that is overloading your nerve endings in that area. Scratching provides a way to break up the sodium deposit and realign the elemental/mineral concentration to a more normal level. So an itch is a build up or change in the flow of chemicals that surround the nerve sheaths, causing the nerves to react in the skin. \n\nThat said, scratching while nice initially often damages the skin and can lead to cyclical scratch/itch/scratch issues, that further irritate the skin and cause greater damage.

It's the release of histamine during the immune response that causes you to itch.

An itch is caused by an irritation on the skin.\nA yawn is caused by tiredness.

is that a dance? do the itch and yawn!!!! if it is then sweet sweet music is the only thing that can cause it.\n\nyawning is the bodys way of increasing oxygen in the blood through a larger than average intake. you yawn when you are tired because your brain sends a signal requesting more oxygen when it is running slowly.\n\nItching can be casued by many things, irritation to the skin causing localised anaphlactosis (allergic reaction swlling, hives, the bodies immune system does not recognise a substance and so sets off an immune response, this attacks the foreign substance and any cells that are affected, the side affect of this is itiching).\n\nAlso itching can be caused by being  overly hot with circulation interruptions causing an itchy recation to the skin and phsychsomatically, ie say to somebody "imagine being covered in ants" the image of this will cause the body to become itchy even though there is nothing there.\n\nif you are itchyt and yawning i suggest that you have a bath, dont watch any wildlife programmes an ants, and go to bed.

The reason for the sensation of itching is not well understood. While itching is the most noticeable symptom in many skin diseases, but it doesn't necessary mean that a person who feels itchy has a disease.\n\nStress and emotional upset can make itching worse, no matter what the underlying cause. If emotional problems are the primary reason for the itch, the condition is known as psychogenic itching. Some people become convinced that their itch is caused by a parasite; this conviction is often linked to burning sensations in the tongue, and may be caused by a major psychiatric disorder.

I was told in an Anatomy and Physiology class by teacher that scratching an itch interferes with the nerve messages being sent by the itch to the brain. So temporarily you don't feel the itch. Putting ice or tolerable hot water on an itch can help similarly.

Most itchy skin (without any rashes, bumps or lesions) is caused simply by dryness.  If you don't already, use a moisturizer daily.  If you do and are still dry, find a different moisturizer.  If the dryness continues to be a problem, see a doctor to rule out illness and a dermatologist for some prescription moisturizer.

Sounds like the start of a yeast infection.  Contact a doctor if this is your first for medication to treat the cause and the itch.

It's were you discharge from your private area. And you ITCH real bad. You can become raw and swollen. If this happens I recommend that you use a ICE PACK and Pain pills. Also call the doctor and he may call you in a perscription that can get rid of it within a couple days. You may even notice a difference in a couple hours of the medication in your system. I also would recommend a anti itch cream the area. I hope this helps

It might be a mild allergy to the sun or just an anxiety reaction.  Whenever I feel my temper flare or feel anxiety or stress come on really quickly I get itchy...but no rash.

You get an itch because there is an excess of dry dead skin and you scratching is your body's way of shedding and getting that dead skin off so the new skin can breathe

Have you change soap or detergent? Even shampoo can cause you to itch.  Also stress has been known to cause people to itch. It is a way for your body to handle it.

Yes thats perfectly normal. Because during your period the layer of skin is shedding and that may cause your vagina to become slightly irratated and cause it to itch. There are creams you can get that you use before your period and that usually stops the itching.

It depends on the type of eczema, but it will not be so much how it looks as how it feels. Dry patches of skin that often look red and inflamed, and which feel itchy. If you scratch it will become even more flakey and sore.\n\nI've heard it called "The red rage" because it can sometimes get worse if you are going through difficult emotions.\n\nSometimes it is a kind of "contact dermatitis" to do with an allergy, say to eating wheat products, or using soap. In this case, think about what products you are using and try changing to allergy free ones.\n\nIt is a horrible condition, but there is a lot that can be done to control it. Start with a consultation with your GP, and if it persists, you could ask to be referred to a skin specialist.\n\nMeanwhile, look after yourself, try using different products and eating different foods, and helping yourself to feel less stressed.\n\nHope this is of help.
