Ruby, go see your doctor ASAP! If your doctor does not want to prescribe antibiotics even with the upcoming surgery, if you have had sinusitis before and know which antibiotics you tolerate well and at which dose, google for "fish meds".
I mean, FFS is so important! You can't let a sinusitis prevent you from having surgery!! If there is a fire, I will indeed grab my passport and the xrays - I can always reprint the plane tickets 🙂 But I'm sure I'll be having nightmare about sinusitis tonight!!
Maybe we'll meet in Buenos Aires? I will be there next week too, but first I will have a consult with Dr DiMaggio. PM me when you're there!
