What a coincidence. I was out cycling yesterday when I felt a "pinching" sort of pain in the lower part of my backside and it felt horrible. I felt this pain at the local university where my boyfriend works and considered stopping and having to drive home instead of finishing up the last 15 miles. But, I went on thinking that it might move out and oddly enough this morning, no pain. Weird. I would like to know the basis for the orthopedists and sports specialists arguments.
