My 9 year old daughter has a bump on her right temple. It showed up a week and a half ago. She has been to urgent care who thought she should use a cold compress and its probably bug bite. Week later took her to her pediatrician and she said thought it may have been bug bite that got infected and she is now on Suprax. Pediatrician also said bump could result from overlap where cranium connects together...but that is usually seen in younger kids. Bump is prob size of nickel. Bump is not red and doesnt hurt when you apply pressure. It used to hurt her when we first noticed it. She weighs about 70 lbs and is four foot 8 inches tall. Thinking I need to make dermatologist appt now because it takes at least a month to get to see dr. Is dermatologist correct specialist to see?
