I am a 44 year old woman who has suffered with numerous medical issues that I believe may be related. I have joint pain, fatigue, nodules that appear and disappear on my elbows, frequent infections(sinus and UTIs with chronic kidney stones) and was diagnosed with a mass in my anterior mediastinum a year ago that is still undiagnosed(insurance issues from hell). I am in constant pain, and had been treated with biologics for seronegative RA(they aren't sure) for a period of time. I have lost weight due to lack of appetite, night sweats that drench me, bone pain, and pain in my lymph nodes. I tested negative for MG, and recently had emergency surgery to implant a pacemaker/defibrillator for Long QT Syndrome, as I coded at the ER after suffering from v tach fainting. Has anyone else suffered similar seemingly unrelated problems like this? I am desperate for a diagnosis as I can't work and my quality of life sucks. I weigh 90 pounds and it's hard to keep that weight on. Thank you!
