@oliviahutson My husband was suffering from the same symptoms except the bzck issues. He visited the ER 6-7 times for 3 months and the doctors could explained what was causing his symptoms because all the tests came up normal except that he suffers from Right heart failure which was being treated. After visiting many specialists to find out the cause of all his health issues we decided to go to Jacksonville Mayo Clinic. His cardiologist diagnosed him with Cardiac Amyloidosis after ordering special tests related to Immunoglobulins/proteins with a special CT scan. His Kappa/Lambda were high and his M protein was just a little high. He is taking Vyndamax for it. The amyloidosis was causing all his symptoms including his Heart failure. Now he needs to go back to Mayo this week to check which type of Amyloidosis he has and depending on the results there might be a possibility of starting chemo to stop the process of proliferation of plasma cells which increase the proteins that cause all these problems. Amyloidosis is a very complicated condition because it attacks any organ including your spine. Ask your physician about this. Hope you get better soon and find solutions. Blessings
