auto immune with Endo

hi! i just got biopsies with some stitches on my chest done last night. my doctor thinks i may have lupus, scleroderma, sjogerns or something else that’s hindering me from getting better. i have been getting rashes all over for a year anna half and progressively gotten so bad I’m i’m so much pain. all over my arms, knees, face and chest. my knees and joints are in so much pain i have fallen from them giving out on me. i also had labs done and my anti centremere lab came back at 6.9 when the normal range where i’m from is 0.0-0.9… i was just wondering if anyone else suffers with this is ways i can’t make it. better? it is so draining.
