It sounds like he has the most important part---you! You are key to his care. Your encouragement and caregiving will truly benefit him. My husband is struggling now due to a lower back issue that has pretty much disabled him in bed. After being passed around by doctors, I went back to the spinal surgeon and pleaded with him to help me find the issue in his lower back and fix it. I explained to him how it was laying my husband up in bed for nearly 1.5 months now and he is unable to exercise to help his PD. I explained how the steroid shots from pain management don't work and only shoot his diabetes into the 400/500 range, placing him at risk for keto and other issues. They previously found a lipoma on the spine, but no one, except 1 doctor who was not in charge, wanted to eliminate it. I was not taking NO for an answer, and the spinal surgeon has agreed to help now. I spent 24 years as a Criminal Investigator and then went into nursing to help people, and I never said no. When they said things were impossible, I showed them things were possible. My husband's journey is my journey too, and I will fight the fight with him!
