Re: Skin crawling sensation and itchiness
It could be peripheral neuropathy if it affects primarily your feet. lower legs and hands. I would expect some level of numbness with it too. If that fits your locations, testing for B12, folic acid deficiency, and thyroid testing and diabetes testing should be done, as well as an ANA for connective tissue disorder. Alcohol excess can cause PN also. You might want to read over some of the posts on peripheral neuropathy to see if that fits with what you are experiencing. Sometimes it is hereditary or idiopathic (no known cause).
