Last yr something similar happened 2 my grson, now again?My grandson had a fever Friday evening and I gave him ibuprofen. In the morning he awoke with a swollen lip. He ate and drank fine until Sunday evening were he was miserable. He couldn't eat or drink without pain. Last year we had a scare. He had fever & we gave him ibuprofen. The next day he had fever blisters on his lips. Next day they were inside his mouth. We took him to the ER and they said he would have to wait it out. The rash is now all over his body. We took him to his PCP and was prescribed amoxicillin. Walking out to leave, the nurse says to us, if that were my child I'd take him to the ER, and so we did. They could not figure out what was going on so they admitted him and did test after test and thought it might be Johnson's Syndrome, which is an allergic reaction to amoxicillin and that scared the hell out of me. It turned out it was not but they told us to stay away from amoxicillin. Now here we are again, fever, gave ibuprofen and now a swollen top lip and he cannot eat or drink without pain. Please help us. My poor grandson is in so much discomfort.
