@formydad Maybe you can ask your mom or dad if massage might help him feel better, both emotionally and physically? There are some gentle massage styles. I know that some people swear by foot massage and the trigger points located in the feet. Acupuncture for the swelling/pain/discomfort? Sorry, I need to think some more on this, and will get back to you!
Please know I am praying for you all and want to help however possible.
