It is hard to list ALL the symptoms that many of us have had.....but we do have an older thread with what we titled
Unofficial Chiari symptoms because even many of the true Chiari specialists will recognize all the symptoms we list.
I will bump it up for you to read.
For me, I did get headaches in other areas then just at the back of my head...but if I coughed, laughed, or had a BM it was always at the back of my head ...this is what is referred to as a Chiari headache....
