My S.O. is ruined from years of construction work. He is unemployed with no medical insurance and has nowhere to turn. He hurts everyday. Are there any programs out there to help these people?

Yes, it is called college, or trade school. He might consider learning a job that uses his head, instead of his back. He can be an estimator, instead of framer. Use your head!

did he ever file for unemployment?

without medical insurance he's pretty much screwed, but id suggest trying some herbs and vitimans, there is vitamins to solve everything now a days.
