I have not idea why my right heel is hurting. I wake up and it feels like I have been poked in the foot with a really sharp instrument. I am unable to put any pressure on the foot. Had the same thing yesterday morning, but still managed to get on the treadmill and walk at a small pace with the incline increased. It seemed to keep the sugars in check. Today morning the pain was worser. I am baffled. It was bad enough to not be able to get on the treadmill. If it continues tomorrow, I will have to take out the yoga tapes and do them. Getting off exercise is a bad idea as getting back in is always harder.
