I just got out of the hospital with severe muscle pain. The doctors said it was from a lack of vitamin d. I told them it wasnt but they treated me for a cf exacerbation anyway. I did feel a little better. I got home yesterday and went to work for 4 hours this morning. I took a nap this afternoon and woke up in pain. My body was really hot and was sweating really bad but no fever. Anybody out there have anything close to this. I know it has to do with my body getting overheated. THANKS KEVIN
