I think that how each one of us would react to something like this happening ( to lens AND camera) is a very personal thing.
Some people would react in a nonchalant way. If it is not , obviously, broken, and it works, go on living with it.
Others, and that includes me, would not feel good about it and from now on start obsessing that every little thing which will happen in future will be the product of what has happened.
From what I see and if you are person type A, don’t do anything, everything works as it should.
However if you are person B, as I am, send it in to have it checked .
