@rbear Thanks for sharing. I have a similar journey except started with skin, joints, then, ILD. Been on Mycophenolate Mofetil for ~15 months now. Lungs and skin have stabilized, which is good. I have ongoing muscle weakness in my legs - quads, gluts, et al. Had MRIs, EMG and they don't see inflammation, just some tendinosis and myopathy. Off to PT I go. I'm normally a very active person - tennis, golf, run, gym regularly. This muscle problem has hampered all my physical activities. Anyone experiencing anything similar? Any advice on relief?
