Hello, I am a fellow member on this site in the std department. I am currently having some problems with my sinuses or so I think. My problem started on the first week of July with mucus or something of it stuck in my throat. It causes me to cough non-productively and forces me to constantly clear my throat. I sometimes get random pressure behind my eyes, the temples of my head (left or right), random aches around the jaw line, These aren't constant problems but they come and go and they are not gradual. My voice gets a little hoarse or groggy like until I clear my throat once more. I have notice my eyes get a little red and have some new veins establishing in the sclera. I get almost a postnasal drip theme in the morning and nasal congestion but they get better during the day. It seems only in the morning and night, the tickle in the throat comes back and postnasal drip occurs. It never bothers me when I sleep. Until recently, I feel I have an ache under my left side of my chest and near my shoulder blade on the left side of my body. I breathe perfectly fine and it is not affecting my abdominal area in any way. Could this be Allergic related? Oh, I do suffer from Acid reflex.
