I work standing alot. at the end of day my feet are tingling and my calves are tight. i notice my calves get tight when sitting in a chair also.

Edema: Standing for long periods causes pooling of blood in your lower legs. That can give swelling, tightness and tingling. Consider getting some compression stockings. Dr Scholl has some light compression knee highs in the women's sock sectiion that may be a good place to start. Firmer/ tighter stockings are available in the pharmacy section or by order. If the issues continue see your MD.
