Hi my daughter has chiari malformation and syringomyelia with constant low pressure headaches that her neurosurgeon is trying to figure out now. She just recently had her shunt changed because it was flowing too fast but low pressure headaches are still occurring. For two days now, she is complaining of her body getting the feeling of hot starting in her hands and moving up her arms then neck and the. Down her body. All the while she gets "goosebumps" but doesnt feel cold. Any ideas or thoughts on this? They also have told us she has pot syndrome. But these last two days of checking her BP and HR, she has been regular numbers.
