It usually starts from an injury of some sort. It causes pain and neuropathy and it can spread to other areas. It's very unlikely that you have CRPS; it's a bit rare; but you definitely need to see your physician.
Have you considered fibromyalgia or chronic fatigue syndrome? Have you seen an internist? They may be able to confirm or rule out possible fibro.
