I'm really worried about this ongoing chest pain and difficulty breathing thats been happening for 5 months, and now theres talk about a potential autoimmune disease. It seems to have been confirmed by both my GP and a Pulmonologist, and theyre suggesting seeing a rheumatologist next. The latest episode was really tough, lasted 12 days with fevers around 100.9 to 102, night sweats, and I've lost about 15 pounds. I'm just trying to understand what might be going on and what to expect moving forward. Any insights?
