My first symptom started in October 2015 was double vision. April of that year I hit my head pretty hard.
I was sitting at my desk working on the computer and all of a sudden my vision went double for 20 seconds. During that month I drank a lot of coffee. I noticed my vision would go double when I did strenuous activities after this. I was doing a lot of push ups around this time and double vision would happen about 10 reps in. It hasn't gone away since. Some days I don't get double vision, other days are worse. Simply standing up from sitting may trigger dv. If I try to pick up something heavy I get a very bad headache immediately and sometimes get dv. Sneezing and straining on the toilet sometimes gives me dv. This year has been worse with the headaches almost every day. I've also been having neck pain and vertigo/dizziness when I turn my head. The doctors really have no idea what is wrong.
First I saw an optometrist. And then a nurse practitioner. I got a CT scan and MRI both without contrast of my head. Nothing was found. Blood work was done with nothing found. This year I saw a neurologist who thinks it's migraines. Seeing another nurse practitioner now. I had a CTA scan of my head with nothing found. To me it feels vascular related. But the CTA seems to rule that out? I am convinced it's a brain aneurysm that wasn't caught. Recently I've been trying to take 325mg aspirin if my headache is bad. It seems to help it but the double vision is still there.
