I had my flu and pneumonia jab on Monday and by yesterday I felt pretty lousy. Sore throat, aches and pains (worse than my usual fibro pains), coughing, I was sick last night too. But the most odd thing is I feel like I am burning up, even my eyeballs feel hot, but my thermometer says my temp is 36.3 which is low? Has anyone else had this before? Burning up but no temp?
