I am feeling random pain in hands and feet that comes and goes very quickly since a week. It's a dull and random pain. I have no history of any injury on hands or feet. I type a lot and use cell phone daily for hours. The pain comes and goes so fast that i can't even note where it was paining but it comes back frequently. I can still do my daily tasks but i m worried why I m feeling strange pain in different areas on my legs and arms spontaneously.
