I am so sorry that you are experiencing all of these symptoms. Since I am not qualified to give you any opinion on the above, I wonder if you have been to Mayo Clinic. The doctors are committed to finding a true diagnosis when multiple symptoms are present. My husband had several puzzling symptoms and we made appointments in our hometown amd nearby cities with many doctors in different specialties. All had differing opinions, and yet my sweet hubby was progressively getting worse. Many medications were prescribed and one - an anti psychotic called Vraylar caused irreversible lost ground. Finally someone mentioned Mayo Clinic and the doctors (neurologist, psychologists, hematologists, radiologists, etc. ) all ran a huge battery of tests and eventually we were told that he is probable for LBD. While it was heart breaking, at least we had a path to walk and time to make new memories. - and most of all- the appropriate medications.
I hope you can get to Mayo Clinic very soon, so you can go forward and manage your symptoms. God Bless!
