What causes itching all over without a rash? - Dr. Rasya Dixit

One of the most common things that doctors ask when they say that I have itching all over the is if there is rash associated with it and when we talk about any causes of itching in the without a rash, what are dermatologists look for? Especially in the Indian population, the rash is not at all visible, that is because we have a more brown skin or more darker skin, sometimes the rash is present but it is not visible to the naked eye and when doctors exam they have a special method of examination where they can pick up the rash even though it is not visible to the common person sometimes we have an infection scabies. It is a very common infection especially in crowded hostels or in schools where there can be very few rash or one or two bites that look like mosquito bites but rashes all over. But if these two conditions have been ruled out, and you have long itching going from weeks together, from months together, then we have to start looking for severe causes. Diseases such as thyroid, liver conditions, kidney failure can all present like itching all over . So if you are getting itching that is not getting better or not having any associated symptoms like very dry skin, then it is very severe that means it wakes you up in the night from sleep and you have to scratch or if it is disturbing your work, then this is the itching you have to get it checked by a dermatologist.
