Individual subconcussive impacts do not cause damage. It is the accumulation of hundreds of them overt a short period ( a month or so) that is a concern.

The rest is just anxiety.

Donniedarko's comment is a great way to look at these bumps.

Keep your appointments. Even if you smashed your head into a brick wall, you should still keep your appointments. Two hours of appointments out of a whole day will not set you back.
