Hi and welcome to the Chiari forum.
I am so sorry ur DD is having to deal with the HA's from this condition.
Depending on her symptoms and how the condition is affecting her, she may not be a surgical candidate....and not everyone with chiari needs surgery...u will want tests to check to see if she has a CSF blockage and overcrowding...if she develops a syrinx or other symptoms then it would need to be readdressed...
May I ask, does she have other symptoms?
A bit of advice I will offer, find a true chiari specialist to ***** ur DD.
We do have a list of drs names that is for u to help u get started to research drs...u may have to travel as we do not have a list for every area....the list is not a referral....just a place to help u get started.-http://www.medhelp.org/posts/Chiari-Malformation/LIST-OF-CHIARI-SPECIALISTS/show/1293483
Too many drs use the herniation length as a means to determine chiari as "borderline" it is not the mm of the herniation, but the shape and if it is causing an obstruction that is of concern,
Pain relief from these HA's is not an easy task...not something in pill form,....relaxation is one way...avoiding certain activities...lifting...we do have a list of activities to avoid in the Health Pages....http://www.medhelp.org/health_pages/list?cid=186
I hope this is of some help to u and ur DD....we r happy to have u join us, but we r not happy with the reasons that bring u, especially when a child is involved.
