I am 13 months post op! The last few weeks my headaches are back with a vengeance! Anyone have this problem. Plus I am having trouble swallowing.
Get back to your doctor. I am not a doctor but I would demand a new MRI of you entire back and brain with and with out contrast. This will determine if any other problems are prevalent.
Number one thing I do for my 11 year old son with Chiari and Syringomyelia is PRAY.
