My Husband has sinus problems.
He is just prone to it.
Sometimes he gets a sinus INFECTION, versus it just acting up.
At that point, he needs an antibiotic.
Just know that, and per his Doctor, sinus infections... can be hard to clear up or immediately. Even if on antibiotics.
Because, the sinus cavity is a dark dank cave.... and even a Doc, if he looks up the nose, cannot see... EVERYTHING in there.
And yes, if one family of antibiotics does not clear it up, then another family of antibiotics needs to be used.
And what works for one, may not for another.
And yes, the lymph nodes, can get swollen, because there is an infection.
IF your neck is sore, then tell your Doc.
But it is most likely due to your sinus infection... and the lymph nodes trying to battle that.
But you should tell your Doctor.
Now about your allergies: do you KNOW that you have allergies and are you taking allergy meds? ie: Claritin, Zyrtex, Allegra etc.?????
Or prescription allergy meds? Or are you just assuming you have allergies?
My Husband as I said, is prone to Sinus problems. But he is not allergic per say to stuff in the air/dust/pollen/etc. He just has sinus problems.
I have seasonal allergies or to stuff in the air/dust/pollen TOO... BUT I do NOT have, Sinus problems.
So, one does not beget the other, necessarily.
I have never had, sinus problems nor sinus infections. But I have allergies.
Bad Sinus Infections... can affect the whole face/neck/eyes/jaws/ears and cause achiness etc.. The Sinuses and the nose/mouth/throat can all affect each other. That is why there are ENT Doctors. Ears/Nose/Throat.
You might want to try Sudafed... with "Pseudoephedrine." At any drugstore you can get it, but you have to go up to the counter and ask the Pharmacy for it. Because it is kept there, not on open shelves. It is non-drowsy and 12 hour. It works well for sinus issues. My Husband uses this, as maintenance.
