Keith,
I'm not your mother but....
I have two friends missing limbs because of chipping or cutting the bone and roughing it.
One lost four toes after a nailing gun mishap, his whole foot went septic after four days. The other lost an index finger after a severe hacksaw cut that went septic. Bone poisoning spreads quickly. These guys were young when it happened, as if that makes any difference. Just sayin.
Be careful and consider medical help,
Rudy
