Trichodynia
Scalp dysesthesia is a Skin disease, cutaneous condition characterised by pain and burning sensations without objective physical examination findings. The pain sometimes is described as burning. Often there is an underlying Psychoneuroimmunology, psychosomatic cause, such as stress, depression or anxiety. Only a few studies have been conducted on this condition. A theory behind the condition is that nerves innervating scalp hair follicles send pain messages back to the brain when the follicle no longer has a hair in it, in a similar way to phantom limb pain. Another theory is that people who have this condition (sometimes called "ponytail syndrome") have super-sensitive nerves in their scalp. In a recent study it was hypothesised that the unpleasant sensations experienced in scalp dysesthesia are the result of a sensory neuropathy secondary to cervical spine dysfunction and chronic tension of the pericranial muscles. 16 patients were treated with a physiotherapist‐designed exerc ...

Scalp
The scalp is the anatomical area bordered by the human face at the front, and by the neck at the sides and back. Structure The scalp is usually described as having five layers, which can conveniently be remembered as a mnemonic: * S: The skin on the head from which head hair grows. It contains numerous sebaceous glands and hair follicles. * C: Connective tissue. A dense subcutaneous layer of fat and fibrous tissue that lies beneath the skin, containing the nerves and vessels of the scalp. * A: The aponeurosis called epicranial aponeurosis (or galea aponeurotica) is the next layer. It is a tough layer of dense fibrous tissue which runs from the frontalis muscle anteriorly to the occipitalis posteriorly. * L: The loose areolar connective tissue layer provides an easy plane of separation between the upper three layers and the pericranium. In scalping the scalp is torn off through this layer. It also provides a plane of access in craniofacial surgery and neurosurgery. This layer i ...
