I have had mono for almost 3 months now, and I can say I'm doing a lot better. But instead of being tired a lot when recovering, I've been have bouts of anxiety. I'll feel like I have a nervous stomach, or butterflies in my stomach for no reason. I had this more intense when I was in the acute stage, only then it caused rapid heart beats and nausea for awhile. I just hope it's not a sign the mono is coming back. Has anyone else experienced weird body sensations when recovering from mono? Do they go away?
