Hello, Welcome to HCM! Cranial arteritis is inflammation and damage to blood vessels that supply the head area, particularly the large or medium arteries that branch from the neck. Cranial arteritis occur when one or more arteries become inflammed and die. It most commonly occurs in the head, especially in the temporal arteries that branch off from a blood vessel in the neck called the carotid artery. However, the condition can be a body-wide (systemic) disorder, affecting many medium-to-large sized arteries anywhere in the body. There are many other serious symptoms of the inflammation . Allodynia is pain, generally on the skin, caused by something that wouldn t normally cause pain. Many people with fibromyalgia report having this symptom. Examples of allodynia are pain caused by mild pressure from clothing, a light touch, gentle massage, or sheets rubbing against the skin. Improper lymphatic drainage in the scalp area thereby not removing waste products from scalp tissue may also be the cause . These waste products might cause some inflammation in the scalp tissue and around the follicles. The inflammation in turn could trigger the pain. Please consult a neurologist to find out if the nerve endings in the scalp area are irritated . You can consult a dermatologist also . Check and control your BP, hypotonia,hypertonia can cause same symptoms. Hope this helps you . Take care and regards ! Dr.Sagar Gaurav Shrivastva
