mjlc: After my craniotomy 2 years ago I had double vision for 3 months. I was told it was because of inflammation from the surgery itself, understandable given they are messing with your brain tissue. Perhaps those shooting pains in your head are one of your cranial nerves going kiddiewampus from inflammation caused by the surgery. I hope things calm down for you soon. Also, I would contact your care team, as others have suggested, b/c you want all your side effects charted.
