hi all. don't know what's wrong with me. don't have any sypmtoms other than horrible headaches that i get everyday and have had this going on for about a week now......very frustrating! do feel like there's pressure on my temples and on my nose at times and sometimes in my upper and lower jaw. also, in the middle of last week, i had a swollen lymph node that was tender to the touch-that went away but no the headaches. what could this be? could i have a sinus infection without having any stuffy nose or anything? could this be a problem with my mouth although i don't have anything that feels wrong with it other than pressure......

please help:) :confused:
