Chronic head pressure with mono?

Okie doke.. so about two and a half months ago, I started feeling this pressure in my head, and became fatigued very easily. I know I posted a question a while ago about it… but anyways, didn’t think too much of it until I went to Las Vegas for equestrian World Cup Finals. I went downhill FAST, and was in bed the entire time. Went to an urgent care center, and the doctor there was a REAL piece of work. Worthless. Didn’t know what he was talking about. Blah blah blah so I drove home and saw my own doctor. Did some bloodwork, and it turns out I have mononucleosis (mono for short)

My question is… well, my worst symptoms went away in about a week and a half. However, I still have this lingering chronic head pressure. It’s not in any certain part of my head, just kind of all over. Is this typical with mono? My doctor didn’t want to do an MRI or brain scan because she checked me over completely and didn’t see anything possibly neurological. I have no pain, just pressure all the time from when I wake up to when I go to bed. I kind of feel a little fullness in my ears as well.

I know none of you are doctors, but maybe if any of you have had this pressure with mono before, you could help me out. It’s been almost 3 months now and it really is affecting everything I do.
