I hit my head and fell on my hip on Jan. 18 and I have been having headaches, fatigue, lots of different aches and pains...I have been attributing them all to FMS or a flare-up--is this just a temp thing, or could it be possible I actually developed or triggered CFS??? Yesterday I also got a sore throat and it still hurts today, now with a cough once in a while. I am guessing this is a cold--but those are the only symptoms...I thought a sore throat was also a CFS thing. I wish I could just figure it all out. I guess I'll know in a few months, if I still feel this way. By then, any head injury type symptoms should be gone and I'll have a clearer picture.
