Hi @susan5051, I can imagine having a tentative diagnosis of disseminated histoplasmosis. @pattymac knows about that first hand. @memw and @rosemarya have also mentioned histoplasmosis before and may have some experience to share with you.

Here is some information about Histoplasmosis from Mayo Clinic: https://www.mayoclinic.org/diseases-conditions/histoplasmosis/symptoms-causes/syc-20373495

Has your diagnosis been confirmed since you first posted? What treatment has been recommended?
