|The Itch Factor In Morgellons Disease 12/1/18|
Itching of the skin is a typical symptom that most Morgellon's Sufferers experience. I found this press release, Study reviews what causes chronic itching and scratching, which is primarily for psoriasis and eczema, however, it states,"Generally speaking, scratching is not very helpful for long-term conditions like eczema or even short-term itches like mosquito bites," says Kim, who co-authored the review with immunology Ph.D. student Madison Mack. 'It's likely triggering more inflammation and, inadvertently, infection. But scratching is very much a reflex; it's hard to tell people not to do it."
Scratching in response to skin irritation damages the outermost skin cells, releasing signaling proteins such as cytokines that activate itch-sensory neurons in the skin. These neurons in turn produce signals that trigger inflammation and scratching behavior.
Itch may also be related to pain. Some itch and pain sensory pathways are thought to overlap in the nervous system. Some research suggests that scratching can override the itchy feeling by activating pain-sensory neurons in the spinal cord that inhibit itch neurons."
