First tattoo this Thursday

I’m getting my first tattoo this Thursday. It’s going to cover most of my upper left arm and up onto the shoulder. (Thursday is the first of two scheduled sessions). I know some people might think this is a bit big for my first one. But it’s what I want. My question is how bad are the first few days afterwards? I have work and appointments scheduled for the next three days afterwards. Is that realistic? Or am I going to be curled up in the fetal position crying for a few days? TIA
