he should have been givin some kind of pain meds after a treatment like that. when my daughter had a small laser treatment done they did give her tylenol but hers was the size of a nickel. listen, you are one of the very few people i have seen post on here whose child had an h on the arm. would you care to contact me? my daughters h was on her right arm and a rather large one. i would love to just exchange info with you and maybe even help you out. email@example.com
or just visit my daughters site below and my email is there too. hope to talk to you soon.
