Wondering if the roots of all my issues might be autoimmune. Can‘t seem to get any clear answers and haven’t been able to walk down stairs using my right knee for 7 years, can only lower with my left knee and even that goes out sometimes. Had Achilles problems growing up, achilles lengthening surgery in 2012, unsure if relevant. Knee findings: trochlear dysplasia, tiny tears in meniscus, signs of a patellar avulsion injury, and focal sclerosis along medial cortex of proximal tibial shaft & a 3cm non ossifying fibroma, plus complete cartilage loss at patellar apex. My knees randomly go out, for hours or days at a time. Findings don’t show much that could cause it and I’m told by multiple doctors it ”should heal on its own” - but it’s been 7 years. My left knee also has decreased echogenicity to the posterior horn lateral meniscus. This makes me consider arthritis or discoid meniscus. All guesswork. If I stand for long times, my hips and knees and lower back hurt SO bad I have to lean on something to hold myself up with my arms, literally have hand calluses from it. Wondering maybe it’s autoimmune, since I have rosacea and thyroid peroxidase antibodies (under threshold for Grave’s disease, in the 20s), thyroiditis, multiple lymph nodes in the neck around 3cm, and have other bone issues (eg. my jaw pops out all the time, shoulder goes out, tailbone pain) and sunlight sensitivity, occasional burning watering eyes, toe cramps, and AWFUL occasional restless leg syndrome (at least that’s what I think it is). My mum is diagnosed with Grave’s disease, among other autoimmune conditions.
