20-year-old with back surgery wanting to be a fire fighter

Hey, I'm Jonathan had a lateral discectomy last week, have had bad back pain and pain down my leg for a year and a half have done 4 epidural shots, months of PT nothing would help the slightest. Just sucks 4 months ago I started the fire 1 and 2 academy to peruse my dream of this career. Only got thought 1 day of the academy before I had to drop it. thought I could do it off the epidural shots. I know deep down firefighting is not an option now but i don't want to believe it. Just can't see myself with a desk job and that's probably where I'll be for the next 30 years with severe back pain and more surgeries by the age of 30.
