The western jackdaw is found from north-west Africa through all of Europe, except for the extreme north, and eastwards through central Asia to the eastern Himalayas and Lake Baikal. To the east, it occurs throughout Turkey, the Caucasus, Iran, Iraq, Afghanistan, Pakistan, and north-west India.he common name jackdaw first appeared in the 16th century, and is thought to be a compound of the forename Jack, used in animal names to signify a small form (e.g. jack snipe), and the archaic native English word daw. Formerly, western jackdaws were simply called daws.
Much like overexcited nerves can cause overuse-related leg cramps, nerves that malfunction for other reasons can lead to cramping too. Osteoarthritis, the most common type of arthritis, is usually categorized by stiff and achy joints.
What causes leg cramps? Leg cramps can occur for no apparent reason, known as idiopathic leg cramps, or as a symptom or complication of a health condition, known as secondary leg cramps. During a cramp, your muscles suddenly contract (shorten), causing pain in your leg. This is known as a spasm, and you cannot control the affected muscle. The cramp can last from a few seconds to 10 minutes. When the spasm passes, you will be able to control the affected muscle again.
