Suggest Cure For Thick Fluid In Ears

It seems as though I have fluid stuck in my ears; I'm assuming it is caused by allergies; however, no antihistimine has helped. The liquid feels like it's very thick, and when I think it's going to drain out of my ears, it does not. At times it moves up to my eyes and my eyelids start blinking furiously so as to rid the eye of something, but it only feels as though it comes out a little and retreats back in. I can tilt my head certain ways to keep it in my ears and move it from side to side; when it feels like it's all in my ears, my sinuses are clear and clean. The next moment the liquid will clog my sinuses and I'll swallow small bits of thick mucousy stuff. It's scary, painful, and nauseating! I just want relief! What should I do?
