How can I stop the shooting pain that starts in the arch of my left foot going up my leg? Please help I can't sleep at night.

Try wearing . A night splint. This will keep your foot at 90 degrees or more acute to the leg. This should prevent arch from cramping. This brace is meant to be worn when sleeping and not while walking.
See below. It may be plantar fasciitis or muscle cramp. Stretch and use an ice pack on your leg before bedtime. If does not work see a podiatrist.
