text: i wake up with a "cramp type of feeling" under the arch of my left foot(6 month's now). what's causing this? for about the last 8 month's i have been experiencing problems with my left foot. it started with a tingling sensation above the middle toe (that nail also seems to have fine cracks in it, the others don't). after a couple of month's, this tingling in the toe has stopped, but now i've been waking up with a "cramp type of feeling" under the arch of my left foot (6 month's now). the pain would go away after walking on it for 30 + seconds.  now i get this cramp and/or tingling in this foot even after sitting or lying down for about 30 minutes. also notice pain (pin point) in top left calf area.  i've asked my dr. but she doesn't seem very helpful and has not sent me for any tests aside from checking the pulse in my feet which she says is good.  i have had some sciatic pain a few years ago (more of a buttock pain), is this related to it? do i have poor blood circulation/clotting? my dad had severe clotting resulting in amputation. i'm a little concerned. arch pain the human foot is made up of 26 bones, 19-foot muscles, 13 leg muscles and 15 ligaments along with over a mile of tiny blood vessels and nerves. the arch forms a bridge between the front and the back part of the foot. it is made up of bones, ligaments and tendons and is subjected to a lot of stress and work. ill-fitting shoes, long periods of time on your feet, and hard surfaces can all cause arch pain. arch pain itself is often an early symptom telling you that the bones, ligaments and muscles of the foot are being overworked and are getting tired. tired legs and feet, foot and leg cramps, and perhaps even low back pain can frequently accompany it.
