I had partials 650 hp, I was off painkillers by day 4 and never really had pain, just discomfort.
With partials it’s the fact you can’t use yours arms very well for a good week due to your pec muscles. It’s annoying, I couldn’t flush the loo, spread butter, drive, get up from the bed lol., whereas I don’t think you get that with overs.
As for the size they defo get bigger as they heal. Xx
