My friend, Eddie, started smoking again about 2 months ago. Last week he mentioned he was having tingling in his fingers and he couldn't feel his fingertips. I told him the cigarettes were cutting off his circulation and that was the first sign of it. (He is a diabetic and has high cholesterol as well)
For once he listened to me and quit smoking.
It is about a week later. He says his fingers are fine now.
Smoking and diabetes don't mix. I watched them take my dad's toes one at a time until they had to amputate his entire foot. He also had a bed sore on his other foot's heel that I took care of everyday for 2 years trying to save the foot.
He died of complications of diabetes which were exacerbated by his smoking.
