Sore afterwards

So I had a quite long session with my progasm last week, but since then I feel a sore spot there the K-Tab was, it’s been a couple of days but I wanted to know, has anyone had that problem.
During the session it came a point where the toy went much deeper than usual causing also a very nice feeling, but thanks to that sore spot I can’t really use it again until it heals.

Does anyone have an advise or tip how to avoid it?
