I am new to this and actually going to a dr. in two weeks who specializes in these conditions. I have been tired for over a year and all I can do is lay on the couch. I ache all over esp. my legs. I get headaches where nothing takes it away and they last for a week at a time. My question is...my family dr. told me to keep a log between now and the appt. to record my body temperature...why? He also did lots of blood work. thanks for any info. on this!!!
