It is a good thing you caught the sinus infection. My mom had gotten a sinus infection that spread to her ears and she ended up with some perminent hear loss. After that she had developed a heart condition. Even more scary my husbands ex-father in law had gotten a sinus infection which actually ate away the bone seperating the brain from the sinus cavity. He already had one major surgery and now must go back for another, very serious and scary, surgery to fix it.
Until this happened to our family I had no idea that a sinus infection could do so much damage.
