Aww, it's horribly painful isn't it. The relief is worth it though when they get the bit out. Mine kept getting infected and ingrown (they were involuted too) and I was referred for nail surgery. I had a partial nail avulsion where they removed each side of both big toenails.
The worst part was the stinging when they put the anaesthetic in, after that my toes were completely numb during the procedure.
I've had issues with mine taking longer to hear though I've been on steroids which haven't helped and have issues with my feet anyway. I had them done two months ago today and only had the day off work after the procedure. I went for the sides being removed rather than the whole nails.
I got discharged from post surgery checks yesterday and they think I only need another two weeks of dressing them (just simple Cosmopor E dressings like a larger plaster) after the bulkier dressing they put on right after it's done (I had to go back the next day to have that changed).
They are tender for a while after the surgery but not too bad so long as nothing is pressing on them, I've only been able to wear roomy furry boots which are really soft and don't press on my toes while they have been healing. It may benefit you being at home a lot as you can go barefoot or wear open toed sandals (not very practical for me at work in the winter :)).
I hope they sort it for you soon.
