Hi! I do not know if I can help, but I will share. My husband has multiple myeloma and amyloidosis. Both are not curable. I went on a support site for his amyloidosis and they gave advice to apply for disability. Well, I did and got him an appt. and the doctors were aware and ready to complete the forms. Everybody and their uncle said how great that I applied and not to get my hopes up! Well to make it short he got it first time out and within three and half months. The only thing they changed was the time his disability started. The date for us was hard to come up with anyways with the diseases he had.
Check the support sites for your dad's illness.They can give you some guidance on how others fare. What are the standards that the government are looking at. They may see it as a partial disability now. How the doctors say it and explain it have alot to do with it too. My husband is now 57 yrs old and retired early from a state job. He was retired approx. two years when we got the first diagonosis.
My husband has good and bad days too. I know patients who have one or both of his diseases and try to work. It helps if the primary doctor and staff are very familiar with doing disability forms too. Let me know if there is something else I can help with. Oh, I did put it in prayer too. If one is not going to get well, I figured how could they refuse?
