I have a history of compartment sydrome /fasciotomy to my left foot. I'm having an "electrical" shooting pain to 3 toes upon plantar flexion of my foot.

compartment syndorme. You state you had a fasciotomy , so there may be scar tissue near a nerve that is being pinched or pressured with plantarflexion. See your surgeon for assistance.
see md. With your hx. Of plantar fasciotomy and compt syndrome i would see your ors.It could be a morton's neoroma or mild swelling in your foot. At any rate it is wise to have it checked out by your ors. Good luck!
