In any case, I found a pretty slick little gadget to help me self-massage (not that kind!) some of the knots and soreness away -- The Stick. This is a semi-rigid stick with 1" plastic wheels along the length. You roll the stick over the sore muscles for about 20-30 strokes. The result is pretty impressive.
I had a guy demo this on one of my calves at the health and fitness expo before the Seattle Marathon (I just shopped -- no marathon). He told me to walk around the show and see if I felt a difference. It was clearly noticeable! The leg he had rollered felt much better. I bought one.
They come in different sizes and flexibility. I have the Original Body Stick. In addition to my workout soreness, it helps with the knots in my arms and shoulders from typing all day. I love it.
