Help my dad

Okay so in 2010 my dad went to work on a farm for his boss , My dads a boilermaker ,steelworker but this was a private job. He was supposed to build a roof for the cars .

He was on the farm for a week . When he got back when he tried to stand up the one morning, and he couldn't walk ,and our doctor didnt work that day ,so he went to a other doctor.
They send him to get x rays done .
So then he went for his first operation
It looked like everything went well .

So after that he was permanently in pain . He kept working for a company and doing private jobs .
So a couple of years later he went back to the doctor, and found out the screws broke and he went back for his second operation.
That same year he also got a pain block injection.
And a in 2018 he went back for a other back operation.
Was of work for 3 months without pay .

.okay so why i started the gofundme is because we just finished paying for the last 10 years of operations and medical bills.
And we had to stop our medical fund.

And know we got the news the company whats to bored my dad ,but my dad should pay to see the dr ,that will decide whether my dad can still work or not .
We dont have that kind of money . And if he get bored he will be left without pay for 6 months.
