Cutaneous allodynia
Cutaneous allodynia Pain resulting from an innocuous stimulus to normal skin or scalp. The stumulus that triggers allodynia is not normally painful. The pain can be provoked by combing or brushing the hair, shaving, showering, wearing glasses or earrings. The pressure of a single strand of hair reportedly can feel like a jab with a white-hot knife. Cutaneous allodynia is believed due to a transient increase in the responsiveness of central pain neurons that process information arising from the skin. It is commonly associated with migraine.

Migraine
A vascular headache associated with changes in the size of the arteries within and outside of the brain. A migraine begins when hyperactive nerve cells send out impulses to the blood vessels, causing constriction, followed by the dilation of these vessels and the release of prostaglandins, serotonin, and other inflammatory substances that cause the pulsation to be painful. Migraine is a genetic disorder that is inherited. A migraine causes mild to severe pain and lasts from 4 hours up to a week. Migraines usually occur 2 to 4 times per month.

Cut
An area of severed skin. Wash a cut or scrape it with soap and water, and keep it clean and dry. Putting alcohol, hydrogen peroxide, or iodine into a wound can delay healing, and should be avoided. Seek medical care if you think you might need stitches, as delay can increase the rate of wound infection. If the cut results from a puncture wound through the shoe, there is a high risk of infection, and you should see your healthcare professional. Redness, swelling, increased pain, and pus draining from the wound also indicate an infection that requires professional care.

Cutis laxa
A dermatologic condition characterized by unusually loose skin which may hang in pendulous folds. Cutis laxa is usually a genetic disorder. A mild autosomal dominant form can be caused by mutation in the elastin gene (the ELN gene). Mutations in the gene encoding fibulin-5 (FBLN5) can cause either autosomal dominant or a more severe autosomal recessive form of cutis laxa. There is also an X-linked type of cutis laxa.
