Hello! I don't know what to do, my daughter is 1.5 months old and she has a hemangioma on her back. We recently had an ultrasound of her head and they said she has hypertonus. This hypertonus goes away if we do massage, but it's contraindicated for us because of the hemangioma. A neurologist prescribed medication. But will this hypertonus go away with these medications?
