i ve had a low grade fever over 2 weeks, 99-101.5 headache when fever starts for its duration, have cold hands feet (icy cold to touch) then I get extremely cold all over. The home temp is set at 84 day and 82 at night. A heavy winter jacket will eventually warm me up. When I m frozen I finally go to sleep but I am also being awakened by horrible leg cramps, sometimes in my calf, sometimes in my knee joint or thigh. I do have RA and been treated for it for 35 years. Currently take Simponi Aria 200 mg, methotrexate 25mg subcutaneous, meloxacam and D3, magnesium, Vit C,
