Touch is a basic human need. That's why a warm touch like a hand, a hug, even a pat on the shoulders can make you feel happy. However, for people who have allodynia, they may be as much as possible to avoid getting in touch with others. Not for fear of being touched, but in order to prevent the pain inflicted from the touch itself — even though it is really just a glimpse. Allodynia can even make skin feel pain when touched by the wind or the clothes you wear. What is the cause?
What is Allodynia?
Pinch or slap is the touch of the skin that causes pain. The pain caused by the or being kicked is derived from a signal sent from the nerve endings of the nociceptor under the skin to warn the brain over danger. The brain then manifests this signal as a pain, which makes you stunned, crying, angry, until the skin is flushed.
But different when you have allodynia. Allodynia is an unusual sensation of pain in the skin caused by a simple contact who is not usually painless. For example, when rubbing the skin very gently or just simply putting a thumb on the arm.
Allodynia occurs due to damage or impaired function in the central or peripheral nervous system, which should help to pass the touch signal from the skin to the brain. As a result, a simple touch that should be translated as something natural or soothing is even misunderstood by the brain as a harmful touch. Thus, there is a pain.
Allodynia itself is different from Dysesthesia, which is a group of uncomfortable sensations in the skin that can be a tangible sense of heat, burning sensation, tingling, amused, Baal (numbness) until the needle is stabbed when touched. Allodynia causes only overwhelming pain or pain when the skin is touched.
Introduction to the types of Allodynia
There are three main types of allodynia, namely:
- Tactile Allodynia is a pain caused by a touch. This could include clothes that stick directly to the skin (especially tighter clothing parts, such as belts, rope bras, or rubber socks on the ankle)
- Mechanical allodynia is caused by movement or friction in the skin. This can happen when you dry your body with a towel, rub the body while bathing, or even air that blows or moves on top of your skin.
- Thermal Allodynia is caused by extreme temperature changes (very hot or highly wanted) thereby causing damage to your tissues. If your hands and feet become blue when cold, you should talk to your doctor immediately. This may be a symptom of a different condition called Raynaud's syndrome.
What are the symptoms of allodynia?
The most common symptom is a pain due to touch stimulation which is not usually painless. You may feel a painful gentle touch. You may also feel pain while brushing your teeth or other movements along the skin or comb your hair. In some cases, you may find the temperature of lukewarm warm water or cold water hurt in the skin.
Depending on the cause of your allodynia, you may also experience other symptoms. For example, the allodynia caused by fibromyalgia often causes anxiety, depression, difficulty concentrating, sleeplessness, and fatigue. If you experience allodynia caused by migraines, you may experience painful headaches, very sensitive to light and sound, nausea, and changes in vision.
What are the causes of allodynia?
Allodynia itself is not a stand-alone disease, but rather as a symptom syndrome that generally accompanies a certain underlying medical condition. Risk factors for the occurrence of Allodynia include fibromyalgia, migraine headaches, peripheral neuropathy (complications of diabetes or other conditions), up to postherquotation Neuralgia (complications of herpes zoster).
How is Allodynia diagnosed?
If you suddenly feel your skin is more sensitive to touch than usual, you can do a personal check first before making sure it is at the doctor. For example, try slowly peeling dry cotton on your skin. Is it painful? Next, paste a warm or cold compress on your skin.
Compresses are usually healing, but if you feel overwhelming pain, make a consultation appointment with your doctor to get a formal diagnosis.
Your doctor can perform various tests to assess your nerve sensitivity. Your doctor will also ask you about your medical history and any other symptoms you may have. It can help your doctor to start identifying the causes of allodynia that you have. Tell your doctor what changes you feel to your skin.
