Hello girls, they said in the maternity hospital that we need to see a neurosurgeon for a scheduled checkup of the baby, but didn't say anything about needing to go to a doctor within 14 days if it doesn't resolve itself. We were told by the local doctor who came home multiple times and touched her lumps that it would resolve on its own, even though I asked many times. Now the neurosurgeon says that only after 3 months, through surgery, can we remove the blood clot. What do you suggest? I'm going to get an ultrasound today, just in case.
