Oh Lila, I'm so sorry you aren't feeling any better. I have suffered with both symptoms before and I feel your misery.
Heating pad is my fix all too. I have used it for ear pain before and it really helped.
My thing for sinus infection, along with good meds is to boil a pot of water, put a towel over your head and let the steam go to work. Drink lots of fluids and lots of rest!
Hoping your feel much better soon
