Hi - I have posted the same question on the sinus forum, but being that it's a relativley new forum, I was afraid nobody would see it, so I'll post it here too, I hope that's o.k. - Basically, my mom dealt with sinus problems all her life, an I started with it in my late 20's (I am now 45). I usually had experienced pressure in the head, or a headache which was remmedied by some sort of sinus pill. Well, the last few days I've been having pressure just behind ONE eye, my left. Plus, I have been experienceing a little blurry vision (not really much at all) and it sort of hurts to read (to move the eye back and forth) - not bad, just a little. The sinus pills haven't really helped with this. Now, to top this whole thing off, my friend told me that it could be a brain tumor! Now she has me all scared, and I don't know what to think! We have been burning insence latley, and have been using some chlorine bleach to clean the house-but, I've burned insence before and cleaned with bleach before and this never happened. How in the world would you know if you had a brain tumor - or if it's just sinus? I know this sounds ridiculous, but I can't stop thinking about this. I have also experienced some lightheadedness and detached from reality feelings (the last few days since I've had this eyeball pressure). I hope someone can help me! Thank you very much! Mimi
