How To Treat Sudden Itching On The Hands And Feet?

Female over 35, came from work after a very long day at work, sitting for hours, had no lunch. Took pantyhose and ankle booth off, wash hands and had a severe attack of deep tissue itching of both hands and feet. Felt like I was loosing my mind. Frantically scratch pace back and forth, soak feet, then dry them and applied lotion, then the phenomenon disappear as suddenly as it came in about an hour.
Should I be worried about some condition that could cause this? Should be visiting my doctor to check on this?
