Polymyositis and dermatomyositis have a distinct pattern of muscle weakness which is why I asked about
those functional tasks. They both hit proximal muscles around the hip and shoulder girdles and those are characteristic patterns of weakness. That does not mean you have either of them as there are other diseases that can produce muscle weakness.
Normal cpk (measure of skeletal muscle breakdown) is about 45-225. People with myositis diseases can have a slightly elevated cpk up to a 1000 or more. For severe cases like mine it went to 13000 and can go even higher.
Here is an article that might help you understand UCTD and MCTD. MCTD is a defined disease but uctd is a sorta, kinda, almost one. I think it is a catchall when patients have some symptoms of a connective tissue disease but the docs can't give a diagnosis for sure. My understanding that those with uctd often morph the disease is something more defined over time.
Mixed connective tissue disease (systemic lupus, scleroderma, polymyositis), Raynauds phenomena, Hypertension, Barrett's esophagus.
