Dermatographia: Symptoms, Causes, Treatment

We hear about more and more cases of skin infections everyday. While certain diseases have very few symptoms that might sometimes go unnoticed.  Dermatographia is a skin disease in which any minor irritation on the skin can cause an allergic reaction. These reactions are usually very mild, with symptoms such as redness, itching and a scratch like appearance but they can be worse at times. It is a rare disease and is mostly resolved on its own. Though the symptoms of this disease are short-lived, there is no specific treatment for this disease. Onlymyhealth editorial team spoke to Dr. Rashmi Ravindra, Consultant - Dermatology & Cosmetology, Fortis Hospital, Bannerghatta Road, Bengaluru, about the symptoms, causes and treatment for dermatographia.

Dermatographia symptoms

People suffering from this this disease would experience the symptoms only when their skin strikes off against a rough surface. These symptoms usually subside shortly. Sometimes, these scratches look like raised marks on your skin, hence this disease is also called 'skin writing'. It is noticed that a person faces more symptoms if he is in elevated temperatures like sauna, hot tubs etc. Symptoms also worsen if the patient's skin is dry and dehydrated. According to Dr. Rashmi, here are the main symptoms of dermatographia:
