Was bit by large dog on forearm 10 punctures total, has been 2 days no sign of infection, moderate swelling but having numbness on the top of my forearm to my two middle fingers... Currently taking antibiotics & anti inflammatory. Does the numbness subside typically after the wounds heal or could it be a sign of nerve damage?
Yes this is a sign of nerve damage.  It may resolve spontaneously or may persist depending grade of injury, which can be measured by NCV. Just start methycobal also which helps to repair the nerve damage.
