Thanks for the advice guys. I finally have it under control and the bump is much smaller now. I'm beginning to think it may be the blade on the HeadBlade that caused it. It's still rather new, but since I shave the dome twice a day, I may need to replace it more often than a standard face shaving razor. It takes more effort now to achieve the close shave I want, so I guess it's time to change.
I'm still learning the ropes. >_<
