So, I got the results of mt MRA and
MRI scans today. The MRA came back normal, so I am very happy to know that I don't have any tumors, AVM's, aneurisms, etc.! My MRI of the brain showed a chiari 1 malformation with 8mm herniation of the cerebellar tonsils with mild compression of the brainstem. Now, the problem is that there was no comparison with my MRI showing my chiari 1 from 2004, so I don't know if the herniation has progressed since then.
