I woke up this morning with a severe headache that later on caused me nausea. For the past couple of weeks my left ear down by my jaw has been bothering me I get aching sometimes and stabbing pain it s not constant it comes and goes. And I also have this bad test in my mouth and it seems to be coming from my nose sinus area. I don t know what s going on but it s beginning to scare me. Also a lot of stomach acid which this has always been a on going problem
