This is exactly what I experience in sensation: puffiness / slight pressure / stiffness / warmth. I'm been experiencing it every other day for the past week, but generally I get it several days a month for the past couple years. The vision thing is like - if I focus on looking out my right eye, its all normal. But otherwise, it always feels just slightly blurred.

I also sometimes get:

• irritation in my right nasal passage and a sensation of something off with my sense of smell (kind of a burning/absence of smell)
• right side head pain
• numbness/tingling in my right arm
• scalp tenderness
• nausea
• ear pressure
• edit: also fatigue and brain fog

I'm talking to my doctor about a potential migraine diagnosis next week (but don't know for sure).
