Recently, I Notice I Cant Stand A Long Period Of

Recently, I notice I cant stand a long period of time but if I walk I have no problem. The problem I faced is I felt my angle and the bottom part of my foot is tight but no pain. And I do not feel any form of tightness nor pain if I walk.

I suffered from this after I slightly injured the front bottom part of my foot after an exercise and undergone a acupuncture treatment.

Doctors have asked me to rest more. I did ..... although its getter better but somehow I just cant get fully recovered.

Please help. Thank you.
