Yellow, nice pictures!
I had my PT eval this morning. He feels the neck, head, and shoulder issue is a combination of things. First is bio-mechanical. Apparently, I am sticking my neck out when I sit and stand. Then, a combination of sitting at the computer, sitting more in general, sitting in my weekend class in April, and the stress of running have all conspired to cause this. He told me I might need just 2-3 weeks of therapy and then he will re-evaluate. I have to stop running until then, which is sort of fine with me, since it gets worse after I run, but I can keep cycling. Now I just have to figure out where I can use my lap top that is more ergonomically correct.
I will probably walk or hike on the days I was running, to kind of keep those muscles engaged.
