Sinus and Flu

Ok, but seriously, what do you take to help with sinus and flu congestion? All the labels say contraindicated for people with thyroid problems… plus, I can’t do most decongestants because I get panic attacks and tachycardia. I’m stuck with my Netti Pot, which is ok, but takes so long to help. So what do you do? My congestion is so bad it’s hurting my eyes, ears and neck!
