I was wanting to know if this could be allergy/sinus related. I thought it was my jaw line but then felt a moveable gland a little below that that seemed tender. My allergies have been really acting up and this tenderness that I am experiencing is only on one side of my face. I also at times feel warm and then cool like my temperature is fluxuating. I been told that allergies can do that, is that true? I know that allergies can make you feel fatigued, but the hot/cold thing? I have never ran a fever, no sore throat, occasional headaches, I sneeze, I'm stffy with a runny nose if that makes sense and I too wake up with a dry mouth because I have to sleep with my mouth opened at night. I also have asthma pretty badly. Can someone tell me if this sounds mostly allergy related?
