I experienced the same too...my feet muscle was in pain after too long walk, and felt the numb if I sat too long. Then I went to massage, I asked them why de hurt?

They said maybe I was obesity, too much eat oily food. But i'm not exactly too fat or obesity, maybe my fitness..

Then when fasting month came, I slimmed down a bit and noticed the pain is no longer felt. My weight also turn down abit. so its all good now.
Maybe try to do fasting, it is good for u.
