Two days ago I began experiencing mild to moderate headaches. They become severe without constant OTC medication. I notices I was having chills and checked my temperature, again it would not go below 99 without medication. The highest temperature I have had in the past 48 hours would be 101.9. Within the past 24 hours my neck has become extremely stiff. It has subsided a with Tylenol, but it still feels like I'm stretching it as well as my back. Also, my lymph nodes surrounding my ears and throat are swollen and tender. Im a little congested as well.
