Hi @jlsmommie, welcome to Mayo Clinic Connect. I can imagine that you are at your wit's end. That's a long and frustrating list of symptoms. First of all, congratulations on making changes to be healthier like losing weight and exercising. Don't give up.
Your symptoms could be everything and anything. It seems like your doctor is starting by ruling things out to determine which specialists to send you to. How soon will you see a rheumatologist? What tests or results led your doctor to suggesting rheumatology?
