my normal temp has been consistently around 96.6-96.8 (97.2-97.3 during ovalution, fluctuating no more than 0.2-0.4 degree throughout the day), and my temperature is 98.6 now and still rising. I m feeling chills, headache, nausea, dizzy spells, sinus pain, and aching all over my body. At what temperature should I consider taking some tylenol for relief? I just need some help to get a little sleep right now. :(
