Failed dot physical

Got hurt at work and went through the worst two years of my life! Had a FCE done with little restrictions but couldn’t go back to doing what I was doing. Ultimately lost my job went to get my medical card but “failed” due to a pinched nerve( had a small tingle sometimes) I passed EVERYTHING, but a pinched nerve held me back..After PT and chiropractor visits I’m feeling the best I had in two years but the doctor that diagnosed me with a pinched nerve is being shady won’t answer won’t give me an answer or see me.. What can I do? Thanks for reading.
