Still having the pain I've reported in the past

When the pain first appeared, it was in my right groin, and I did extra stretches of the groin. The pain then moved to my right buttock, and I did extra buttock stretches. Now, the pain is in my right quad, and I'm doing extra quad stretches. During my run, when I stopped as explained above, I stretched my quads, and during the last mile on the southbound part of the run, I stopped several times to stretch my quads. I've only been stretching on days that I run (three times a week), and I'm going to form a habit of stretching every day, with extra stretches on my groin, buttock, and quads.
