Re: tingling on the back right side of head
I would get this checked out. The first health problem I thought of was Shingles.
A shingles outbreak is a viral infection that is affecting roots in the nervous system. When the virus flares up, it will create a rash that spreads in a band like form across one area of the body. Most reported cases of shingles are in the older population, or those who have a weakened immune system. This weakness could be from medications, stress, or other factors.
Symptoms and signs of shingles to look for include:
* Burning pain, itching, tingling, and extreme sensitivity or numbness in * some part of the body
* Blisters filled with fluid that are combined with a red rash
For the most part the shingles break out will be on just one side of the body. In many cases it will spread from the center of the back around one side of the body to the breastbone. It travels along the nerve that goes around the body in that area.
Often the shingles break out on the head, around one eye, or just on one side of the face or neck.
While the shingles out break looks much like chickenpox, is does not act the same. With chickenpox, the first outbreak is the worst, and often there are no others, or they are mild outbreaks. With shingles the opposite is true. It causes more pain and irritation in subsequent outbreaks.
Possible Shingles Complications:
POST HERPETIC NEURALGIA
One you have an outbreak, you may develop Post herpetic neuralgia. The symptoms of this ailment include pain, headaches, and nerve problems. Once a person develops post herpetic neuralgia, it will last at least a month and can last much longer, for months or even years. Those who are at the most risk of developing this complication are those who have severe pain and rashes during their shingles outbreaks and those who are over the age of 50. For the most part post herpetic neuralgia develops on the chest or forehead and it can be so painful, it may stop you from completing daily activities such as sleeping or eating. If it lasts a long time, it can also lead to depression. While post herpetic neuralgia is hard to treat, it can be avoided by getting early treatment of shingles. After it forms, many medications such as anticonvulsants, antidepressants, and opioids, can help in lessening the associated pain.
This complication is a blistering rash that is painful and can spread across larger areas of the body. It can also have negative impact on the health of many organs including the heart, liver, lungs, pancreas, intestines, and even joints. If the infection spreads to nerves in the body, it can also affect motor skills.
If shingles affects a set of nerves that form in the brain, there can be cranial nerve complications, which can include blockage of blood vessels and inflammation.
HERPES ZOSTER OPHTHALMICUS
Another complication is Herpes zoster ophthalmicus. This form of herpes is caused by the varicella-zoster virus, the same virus that causes chickenpox. When this virus takes hold, if it affects the trigeminal nerve in the head it will likely be noticeable by a rash around one eye, or across the cheek, nose or forehead. The rash is accompanied by discomfort including itching and tingling. If it is centered around the eye, it can be a threat to eyesight.
