Causes
Common causes of hallux rigidus are faulty function (biomechanics) and structural abnormalities of the foot that can lead to osteoarthritis in the big toe joint. This type of arthritis – the kind that results from “wear and tear” – often develops in people who have defects that change the way their foot and big toe functions. For example, those with fallen arches or excessive pronation (rolling in) of the ankles are susceptible to developing hallux rigidus

Raynaud’s phenomenon is a condition which results in a bluish-white discoloration of fingers and toes, often as a result of exposure to cold. Stress, smoking, and certain medications may trigger or worsen symptoms. The color change, which occurs from spasms in small blood vessels, becomes red and then returns to normal when blood flow resumes.

The condition most often affects women, with symptoms varying depending on the severity of the condition. Because there are no specific blood tests to diagnose this condition, the diagnosis is based on symptoms.

However, your doctor may order blood tests to determine whether the Raynaud’s phenomenon is associated with certain autoimmune diseases or other medical conditions.
Treatment for Raynaud’s phenomenon is aimed at prevention and protection of the digits.
