I cut mu hand on the piece of steel on the shower door Friday night right on the bottom knuckle. Today it along with my index finger and left part of my hand is swollen. I can barely move my index finger. Swollen part is warm to touch. Should I call the doctor in the morning? Tetanus shot 8 years ago.
Tetanus shot 8 years ago is actually not enough reference to determine whether you are still protected or not. However, you should certainly visit your doctor, and antibiotic treatment will probably be necessary.
