My daughter, 8, has a dent in her skull on the top to the right of center. It was not there before. She was hit by a golf ball hit off a club at close range about 2 years ago. She had a big bump at the time and a lot of pain but it all went away. 4 days ago she had a headache that lasted for 2 days, gave her tylenol and Benadryl nothing helped.Then she found the dent. It hurts to touch it. Any thoughts?
