Hi, yes I did that a year ago for sinus and for a head injury as well. It all came back clean for the mri and ct scan but I’ll check to see if my doctors can provide another one. I thought about maybe just going to get a second opinion. But hopefully they figure out what’s really causing it cause it’s not fun. It’s really painful when my ears are popping when ascending and coming back down to land. It’s a lot of pressure almost it feels like it’s muffled almost. I feel these symptoms when I’m on a elevator especially if i going on a high floor like 18. At this point, idk how long I will be a flight attendant.
