Say you wake up in Vail and itâs snowing hard. If the temperature at the base is 20Â°F and the summit is about 3,000 feet higher, then you could estimate the temperature at the top would be about 10Â°F (3,000 feet elevation change at 3.3Â°F per 1,000 feet equals about 10Â°F temperature decrease).
Crepitus is the medical term for cracking or popping sound in a joint such as the knee. Learn about crepitus pain symptoms and treatment in this article.
In orthopedic medicine and sports medicine, crepitus describes a popping, clicking or crackling sound in a joint. Joint popping sounds may mean that air is moving in the joint, which is usually harmless. People most often notice crepitus in their knees, but it can also happen in other joints like the shoulder, elbow or neck. Crepitus with pain can be a sign of wear and tear or injury. If crepitus is painful, you should consult a doctor.
