painless

A painless experience or procedure doesn't cause any hurt or discomfort.

When we talk about something being painless, it usually means that someone didn't have to go through any suffering or distress. For example, if you're at the doctor and they tell you that a shot is going to be totally painless, that's a big relief! On the other hand, medical treatments can be painful for some people, so when something is described as painless, it means they didn't have to deal with any of that. The word 'painless' can also describe situations where someone had to experience an unpleasant or difficult situation without feeling anxious or worried - like a person who's going through a tough time but still manages to stay calm and collected.
