Prior to my decompression I had awful headaches, but never did sneezing bring one on. Today I sneezed and for the first time it felt like someone yanked on my neck and spine. I kept going about my business and after a few moments, the Chiari (back of head) type headache started. How strange is it to not have had them before surgery, but now to have it?!
I haven't had the surgery yet, but I do get pressure headaches when I sneeze. It's awful! I hope yours was just a coincidence...
