Hi, I am a nearly 72 yr old,40- 45# overweight, relatively healthy female. I take no meds except, Recently started on a Spiriva Respimat inhaler - 2 puffs qd, due to recent dx of mod. copd - following an ekg, neg, stress echo, cxr and chest CT. 2 LL nodules - No lesions. I experience intermittent episodes of bi-lat arm weakness/fatigue - and bi-lat leg weakness/fatigue - not always at the same time, but sometimes , overwhelming. I was dx'd with PMR in 2001, after a "flare" . I do frequently have some nomal age related joint aches and pains. Could this weakness / fatigue be related to the PMR ?
