Novocaine Injection: Understanding Post-Injection Swelling & What to Do

Yes, it is possible to get a bump after a novacaine shot. This is because the injection of novacaine can cause some swelling and inflammation in the area where it was administered. The bump is usually small and will go away on its own within a few days. However, if the bump is large, painful, or persists for more than a week, it is important to see a doctor to rule out any other potential causes.
