Hi. I’ve had problems with my muscles for a few years My muscles were just fading away with no strength. Standing after sitting my thighs would burn. Back pain also. My thighs will barely support my body weight. I’m 63 and this started about age 56 …. Tiredness comes with this. Please note I have not officially be diagnosed but in the process of getting a diagnosis. I have in the last 3 months started running fever low grade at nite. 6pm to 9 pm Like clock work. Been to many drs but to no diagnosis. Recently found ibm disease and read for hrs on it. Every symptom I have it’s fairly and trying to find out more about it. I’m fairly active ride motorcycles and love working on shipment. Recently I was diagnosed with arthritis. But leg weakness is real. I could press 500 lbs in high school But now I can hardly go up steps My blood work show very high creatinine levels and have been high for years Wanted to share. This with others to see what else I could find out Thanks. Bill
