NY, if the lump is going down, I'd do a wait and see, but hold off on more riding in the meantime. Going to the doctor, even for routine checks, is on my list of most hated things to do.

We had a rare tornado over in the northwest part of Wisconsin, last night, and it killed one person and injured others. No tornadoes for us, over here in the northeast part of the state, but lots of T storms and rain and much more on the way. My trails are getting mushy, but are still ridable. My goal is to spend an hour, every day, on trail work and add in some road work when I can. Doing both seems to keep me in the best overall condition.
