Put my back out at work, and was on cherrypickers at the time. Got the customer to help me stow the machine and got myself in the cab and was OK sitting up and driving but that was it.
Back at the yard I managed to get my gear out with some colleagues help and was driven home. Had told the office but they were disinclined to beleive me. It’s not like I’d had ANY sickies with that company even. Went straight to the Doc who got me a sick note for a week and got me over to a back doc privately directly (that afternoon) who gave my back a few stretching exercises and I felt a crunch and a pop and then I could move again!
Sick note was for 4 weeks, took that into the office. Offered to only take a week sick leave to rest my back but the doc said I was to keep it warm with pressure off it so light duties after that. It was about then I reminded her that I was off in a week for 3 weeks in Spain for a family holiday…
Also came down with food poisoning a few months later, well, some bug. A weird one. I got weak at work and struggled to do anything. The return journey had me feeling so tired I could barely do anything and had to stop twice on the way back for a nap. Ate normally, enough fluids in me and slept normally overnight. Got back to the yard and sat down in the office waiting for the boss to get the paperwork done for the drivers the next day. I had told her I couldn’t work as I was struggling to stay awake so she gave me light duties.
Woke up to an ambulance crew giving me oxygen and some reflex test. Trip to the hospital, a few tests, and sent home later. That was a Thursday. About the Tuesday I started to feel more alive again and ravenously hungry. The kitchen was a mess and I’d run out of clean bowls and cutlery and all my tinned goods and cereals had run out…
Back at work on Thursday and was given a few ‘long’ runs to test I was OK and that was it for a while.
As for accidents, well.
I’ve had my shoulder yanked out of its socket by a curtainsider… That hurt, was off for 4 weeks. Broke my mobile, landed on it
Office very supportive, but they sent a 4x4 HGV to bring me home. Ok, one armed, weak and feeble, how the heck do I get up the 5 steps to the cab■■?
Thankfully the driver was a strong bloke 
Another time I neglected to look up as I jumped between two cherrypickers parked side by side and hadn’t noticed the driver had cradled the boom. Hell that hurt, and apparently was chucking the red stuff out everywhere. Dribbled it all the way inside to the office to find out where the first aid box was then had to self medicate.
Got the smelling salts out as well as the boss had collapsed at the sight of blood, and felt fine after a while so got on with some driving…
Look where you leap, don’t walk into danger without looking, metal vs me and metal will win…
Not done much tramping yet but have been mostly day work with occasional overnights… Perhaps I don’t count?!
