Was running in hills, twisted left ankle, felt INSTANT pain, it appeared to pass; continued walking until I reached my car. About 2-hrs later removed shoe n it exploded in size. Currently unable to walk on foot, feel tingling on front of foot just above bend in foot. Currently have foot elevated, compression wrap n ice bag. What I am feeling: pain, unable to put pressure on foot n tingling (using cane from unrelated injury) to balance, is it a typical strain? LW
