During your recovery have you gone on a screen fast at all. My husbands doctor would allow no screens until he was symptom free. Now, of course, that isn't always possible if the symptoms do not abate for a long time.

Even after my husband had a setback and the symptoms didn't last as long, we were very strict about any screen time. He couldn't completely eliminate it again as he was back at work.

I read an article from a doctor who treats concussions in mostly kids I think. He takes them completely off of screens and when they follow it, they show improvement. He only had one kid who didn't improve as much but, turns out, he was using his phone and didn't realize that was a screen. I don't know the severity of their symptoms compared to your but, even as a person who doesn't have PCS, too much screen time affects my eyes and gives me more brain fog.

I hope you feel better soon.
