Hi and welcome to the Chiari forum.
Surgery is done only when ur condition is such that it is impacting ur overall health and well being....and u may learn u have a few more symptoms then u think u do right now....as the symptoms cycle and u may have chalked them off to being something else ....it is not easy to connect the dots and see what all is chiari related at first glance.
U do have a dr right there in Boston, but I will suggest u get opinions from a few drs to see who u r more comfortable with.....
What ur drs should do next is check u for related conditions, and see how ur chiari is affecting u...does it obstruct CSF flow, do u have a syrinx, tethered cord, Ehlers-Danlos, sleep apnea,ICP,......head aches r but one issue we deal with.
We do have a list, and it is meant to aid u in ur research of drs, not as a referral........
