Hey, guys. Today I was diving with my buddy and I noticed I could only get to about 30-35 feet before my ears would just have a ridiculously sharp pain. I just couldn't equalize completely. I think I have a sinus infection(been really stuffy lately, along with everybody else at my school) as well as a throat infection(because I was spitting up small amounts of blood.). Would a sinus infection keep me from equalizing completely? Or was I just doing something wrong(pinch-n-blow technique)?
