Whatever the cause, redness is primarily due to widening of the blood vessels allowing more blood to flow just under the skin of the neck. Less often, redness can be due to a burst blood vessel where small amounts of blood empties out and collects in the tissue of the skin.
It is known as hematoma. Eventually this blood will turn a dark red to purple and brown color. Often there are other symptoms that may accompany this redness, such as swelling, burning, pain, itching and heat over the affected area. In most of these cases the redness occurs without other skin symptoms like itching, burning, swelling and so on.
However, with pathologic causes there are usually other skin symptoms that we often collectively refer to as a rash. It is a result of inflammation where inflammatory chemicals are released at the site. This causes the blood vessels to widen redness and heat , become leaky so that fluid can empty out into the tissue spaces swelling and for specialized receptors at the site to become activated burning, pain or itching.
An allergic reaction is one of the common reasons for neck redness. It occurs when there is contact with an otherwise harmless substance that incorrectly triggers immune activity. If it is localized when the skin on the neck comes into contact with an allergen then it is known as allergic contact dermatitis. This may occur with an allergy to certain textiles, skin creams or other substances that make contact with the skin, and often with an allergy to certain metals found in neck jewelry.
Sometimes the allergic reaction is systemic in that it occurs throughout the body when the allergen is ingested or inhaled. Picture of allergic contact dermatitis. An infection of the skin of the neck is not uncommon. It can be caused by a number of infectious agents although most are due to bacteria, viruses or fungi. Bacterial infections may be limited to the skin of the neck impetigo or affect just a hair follicle folliculitis.
If it extends deeper into the subcutaneous tissue cellulitis then it can be very serious. Ask a Doctor Online Now! Picture of folliculitis. Joan was having someone do research on the red spot. There were several reasons for a red spot at the nape of the neck found when you google, but after reading them, I didn't see where they would apply to my husband. I still think that there may be a connection, but it may take years to discover it. If I had the time, I would do an Excel chart and try to put all of this together.
It's got to be of help to those researching Alzheimer's, but I don't. Maybe after Yes, my scientific researcher came up with a definitive answer on that one. It is called a "stork's bite", and it is a birthmark, having nothing to do with AD. Sid's is rather small. By the way, my scientific researcher besides Sunshyne is my college roommate who has a Ph. D in biochemistry - we reconnected via e-mail when I let her and everyone else know about this website. She has been a great help.
Joang, i dont buy the storks bite theory as many of our spouses have not had this from birth.. And wondered about my Dh. Unfortunetly I can't check his head as he is down in Denver visiting his Mom for a few days, but I am sure he has the red spot.
And being a hairstylist I have seen a lot of birth marks and this one is very different. And the fact that my family has some really off the wall birth marks so the birth mark topic is always a good subject. I am with divvi in that I think there may be more to it. Hopefully someday someone will actually investagate it further. I agree with divvi. My husband did not have this mark as a child, nor when we married. It came a few years ago.
Definitely not a birthmark. I'm open to other explanations, and given the number of AD patients with this mark, there has to be something. No one has brought it up with AD patients before us. We're pioneers! CommentAuthor scs CommentTime Apr 3rd This is crazy Know I have seen it before but am pretty sure it was not there a few years ago. Stumbled on this thread.. Need to watch more closely and see if it comes and goes. To my knowledge, most of the common AD drugs do not cause vasodilation.
Need to do some investigating! Those of us who have been around for a while remember subjects discussed before and like to include new folks in old discussions. Pretty neat-eh what? CommentAuthor scs CommentTime Apr 4th Not sure what I like best reading about You are all pretty special All good! Irritant contact dermatitis is an inflammatory rash caused by direct chemical injury to the skin. Burning or stinging sensations are significant symptoms that victims experience.
The symptoms come quicker than the reactions due to allergic contact dermatitis. Excessive water exposure, acids and alkalis can all result in skin irritations. Unlike allergic contact dermatitis, the irritants causing inflammation is an injury to the skin. To get rid of inflammation steroid solutions are normally prescribed. In case of a chronic irritation after which lesions develop, skin protection is a must.
Psoriasis is a non-contagious chronic skin condition that never goes away completely. According to Dr. Chris Iliades , when you are suffering from psoriasis, the immune system sends signals to your skin that speed up the production of skin cells. There is no exact cause but several trigger causes include severe sunburn, stress, wrong use of corticosteroids and excessive alcohol consumption or alcoholism.
Most types of psoriasis result in an inflammatory rash that causes itching. Pain is common. Certain types of psoriasis require immediate medical care when there is a flare-up of symptoms. There are several therapies that doctors put in place to address the problem. Most treatment options aim at restoring skin texture and reduce the itching or kill the pain. In many cases, dangerous types like erythrodermic psoriasis involve systemic treatments after dermatological evaluation.
Another cause of a rash on the back of the neck is the lichen simplex chronicus. According to Skintight, it is an itchy skin condition causing thickened skin at the areas of skin injured by repeated scratching and rubbing. It almost always begins with itchy skin and thickening occurs later on.
Itching may be occasional and sometimes increase while resting or during the night. As the name suggests, LSC sounds like an infection but is not primary. The common causes include skin conditions eczema, dry skin and bites. Home remedies for this condition may help. These are mostly moisturizers or symptom relievers like oatmeal washing, aloe Vera and pure oils such as extra virgin oil or vitamin E oil. Medical treatments include numbing injections, anti-itch medicines such as hydrocortisone creams prescribed by your doctor.
Skin conditions like eczema require a close examination by a dermatologist. If not diagnosed identifying and treating such conditions would be a major challenge. Common procedures involved during diagnosis are physical examination or under a microscope.
DO not be afraid or become worried when asked for a blood test, scrapping from affected areas or a biopsy some dermatologists may ask. Please answer all questions asked to the best of your memory or knowledge. As seen above, itching can accompany rashes.
