@klsmidwestmom,

Endocrinologists are much more than diabetes doctors. They are involved in the entire hormone system of the body. They are good doctors to meet especially when you have a variety of problems. Here is some information about this specialty from Mayo Clinic's website, https://www.mayoclinic.org/medical-professionals/endocrinology/news/endocrine-practice-changes-during-the-covid-19-pandemic/mac-20490513

No, I'm sorry, but I've never had any biopsy of the lymph nodes so I can't help you with that question.

Keep posting questions and concerns as you wait for answers.
