Hi, i have been having light headaches everyday for the past month. I've been under a lot of stress lately so I just attributed it to this. I started taking aspirin 81mg when needed...about every four hours and the pain usually went away. Tonight, I noticed that there s a bitter, almost metallic taste at the back of my throat. Also my front teeth seem sensitive. Oh, a few days ago, I had temporary numbness on the right side of my face. Just the cheeks and the lips. Does this sound pretty typical of tension?
