In regards to op post, I don't think my business would cope, and if I had an injury like yours frank I would consider selling up immediately, that's not to say you should.
I had a load of kidney stones removed a few years back, was having major stomache ache and always had a stitch in my side, had first session of treatment in April and last stone removed in October, was a year from hell, had to have a 2 stents fitted, 1 up me little fella to me bladder other from bladder upto kidneys, was told to have time off work but couldn't as to busy, anyway nearly jacked the lot in, it was that bad. 12 stones in total biggest ones was between 17mm -21mm.
Not only the medical side but the stress it causes it's something I wouldn't go through again, and should anything medical or injuries I would put a for sale sign up the next day.
I do wish you the best recovery and will also be making a payment to your online account
