I woke up one morning feeling extreme pain around the right side of my nose and under the eye (I was also lying on my right side). It was literally throbbing. I had to get up and walk around. After that the pain and pressure eased up and I took a pain reliever. I went back to bed and laid on my left side, the right side pain went away, but the congestion went to the left side. I stay congested all year long. Sometimes I have an annoying type of pain in the top of my head that seems to be related to the congested. I was diagnosed back in Feb with sinusitis but I took antibiotics. Can this still be sinusitis or allergies or something more serious?
