I have had a stuffy nose for several days now, and have been getting severe sinus headaches/migraines (including at the back of my head where it joins the neck) almost every day for over a week. The past two days I have noticed an immediate buildup of pressure in my head (front and back) and a smell of chlorine/ammonia when I bend over (all the way or just getting my son in/out of his car seat). Is this normal or do I need to be seen? 32yo female, 5'10, 260lb with pcos w/ insulin resistance, endometriosis, 2 degenerated discs (L4,L5 and L5 bulging).
