My 5 yr old son has a rash/hive on his inner thigh that I believe to be ringworm. We went to the doctor today, before I knew about the rash, and the PA (there is no MD) said his wbc s were elevated and his ear canals were agitated and red. We were scripted a braod specrum antibiotic and sent on out way. I know that this won t help a fungal infection and I am hesitant to give it to my child and wrecking his flora and ph..Any advice will help. i have covered the rash with tea tree oil, neat.
