###Human: I am having tenderness with itching below left shoulder blade. Why? ###Assistant: Hi. With the description given, it looks more of a neurological problem rather than a skin problem. If there are no rashes and only tingling sensation and pain, etc., over skin of lower shoulder blade, then most likely you are having notalgia paraesthetica. It is a superficial nerve disorder of the skin. For now, you can try a local anesthetic cream called EMLA which has Lidocaine and Prilocaine. Try it for a week or two. If no improvement, then please consult your local physician. You may need some oral medication which is not available over-the-counter.
