question: Hello doctor, I have been having episodes where I will have periods of dull pain over my left eye, the area where the bridge of my nose meets my brow bone. At the same time, I am getting a tingling sensation in my right groin at a very specific location and not a generalized tingling. The periods of pain and tingling used to last for 10 to 15 seconds and would occur maybe once every few days for a week or so and then disappear. They were gone for about a month, but now they have come back and are occurring once every few days for the past one week. They have happened mostly at night or when in a reclining position and have recently woke me up. They tend to coincide with when I am having some amount of post-nasal drip. When I am feeling the pain or tingling I have not found anything that lessen or quicken the pain or make it worse. When I press on the area above my eye where the pain is, it is tender even when not experiencing the pain or tingling. I have not experienced any nausea, headaches, blurred vision, etc. What could be causing this?
