I have sinusitis, but I am a sickly child with other possible ailments. I have headaches in the side or back of the head, along with sinusitis headaches, sometimes I just can't seem to concentrate or focus my vision on bright images, I often have aches in various parts of my body, I frequently have headaches after exercise, I feel I might have depression, anger issues, or too much stress, bad breath- though this might be due to sinusitis, and I often have stomach-aches. Do I need to be worried, or is this o.k.?
