Knee is now fine, after getting it done, hurt like a bastard though. Hurt when went to walk, or stand or sit on Monday evening, night and Tuesday morning. Around late Tuesday afternoon it started to ease. Yesterday was fine and today no problems. (Got it done on Monday the 8th of Jan)
It's healing well, swelling has gone down from pics that I had taken, despite everyone telling me it will swell up. Mine didn't.
I was worried about getting knee done because of what I had heard from others, including tattooists. But, for me, it's no bother at all. Looking forward to getting the other one done now.
Edit: I will add that I put no ice on my knee at all. I don't put any ice on my tattoos.
