Why do my legs start to itch after standing for to long? Seems very odd.

Circulation. While there may be other answers, mostly commonly, it is a matter of your blood not circulating properly & getting stagnant b/c you are not moving around, esp if you are overweight &/or have varicose veins.The purpose of circulation is to bring in oxygen and remove waste products. In my residency standing in 1 place for 8 hrs gave my legs big pain. We must always be moving! circulate ur blood!
