Virus or Stenosis?

I'm off Baclofen again... it didn't seem to reduce my spasticity and I was starting to feel tired again.  Since that is a possible side effect of the drug, I thought that was the cause of my increased dizziness and fatigue.  However, I've been off Baclofen for almost two weeks now, and I've had some days of greatly reduced energy, seemingly tied to a pressure I feel in my head, behind my right eye.  Could it be increased stenosis of my right jugular, or some kind of low-grade virus that just won't let go?  Just when I figured it couldn't be a virus that could last so long without turning into anything more, tonight I'm starting to feel something in my chest.  Whoopee, I think I'm getting a cold!
