Hi and welcome to the Chiari forum.
Chiari is one of the most overlooked DX even when it is as obvious as an elephant in a living room...too many Drs are not well informed or experienced with it so u need to locate a true Chiari specialist...have more testing to see what all is going on with u ...just having a Chiari DX is not enuff.
Those of us with Chiari are prone to auto immune conditions and connective tissue disorders....
One auto immune conditions many of us have is Hashimoto's thyroiditis...which can have and effect on ur hair.... most Drs do not look for an auto immune thyroid issues they only look at TSH which can appeaar normal while an issues is still affecting u....
Chiari symptoms do not respond well to meds....if nething if they do it is short lived.
It is also best not to build a tolerance to meds now, bcuz should u need surgery later u will not have a med that will help with surgical pain.
There are things u can do to help with the HA's and other symptoms u may have....check out the Health Pages for a list of activities to avoid as well as a List of Drs for u to use to research Drs..as the list is not a referral, nor an endorsement.
