bruised heel?

hi y'all, whilst i wait for my dr's appt, i wondered if any of you may be able to shed some light on a heel injury.

left foot. heel. not painful to walk on, touch, poke at or anything. but point my toes towards my head and oh lordy the pain right on the bottom of my heel!!

now ive not been over zealous with excersise, i havent strained myself that i am aware of and i certainly dont recall hurting myself.

any ideas... its not a pulling pain, and my toes are equally mobile, there is no joint pain, ache or any thing, i think its bruised but not sure. drs will give me a better idea but its a week to wait for my appt. x
