Hi and welcome to the Chiari forum.
I agree with Dana that u need to talk to a Chiari specialist.....a chiropractor is not the right way to go as it can cause more damage,many times it can give short term relief....but it can also cause more compression...so it is not worth doing.
I am sure the issue is having Drs that r not experienced with Chiari, so many of us r told to take meds and get the brush off....
Please see the list of Drs the members compiles to help u get started in researching Drs, keeping in mind they r not all true chiari specialists, nor is it a referral for ne on the list.
Let us know if u need help locating more info,, but the list is in the Health Pages as well as some tips on activities to avoid with this condition and a few others.
