My son has a scratch on his face, above his lip, for about a week. It can't heal complete. We went to see a doctor last Monday. He prescribed an antibiotic oitment. Then he checked the ear, found ear infection, and prescribed Cefdinir for it. Since my son doesn't show any sign of ear pain, we held off on the antibiotic until now. However, the scratch still can't heal completely as of now. The surface dried up, peeled off, then it showed the wet and red spot again. This process happened for 2 times. What should we do? Give him Cefdinir? Would it also help with the scratch infection?
