My husband has a plethora of symptoms. Painful joints ( no arthritis). Out of breath, weak muscles and is often falling down. Has had an increase in memory loss and has suddenly started slurring his speech (which seems to come and go.) He s always exhausted and can barely do anything physical. He recently had lung X-rays (negative results), has been diagnosed with a stiff heart but the Dr isn t treating it...? He was not aware that he was slurring his speech. I m just in need of a direction to investigate.
