Quite by chance I found myself researching itchy heels. The is apparently a very common complaint, and those affected by it can't seem to get it diagnosed. It seems to afflict them when they are not standing, and is apparently worst when they lie down. They have trouble sleeping because the itching is so intense. I found a site with a couple of hundred entries from sufferers. There were only two helpful entries. One was from a podiatrist who claimed the cause was neurologic. One was from the only person who seemed to have been diagnosed correctly. She was told her calf muscles were entrapped. After surgery the itching went away. The tests for those sufferers whose doctors looked for a neurological problem came back negative.
