Positional headaches occur when upside down (in yoga). Started about 6 years ago, had an MRI and EEG. Both normal. Over the years, headaches persisted but recently got worse.
First an eye exam - doctor told me that optical nerve was slightly enlarged, did a glaucoma test, came back negative. Then family doc referred CT scan, came back showing mass in right orbital socket, not attached to tear gland. Recent physical came all normal results. What could this be?
