Yes, congratulations, AZTIMM! Very nice accomplishment.
Separately, I had a recent appointment with my doctor, and asked him about that area on my back upper right arm, and he said it's nothing to worry about. And I'm not, though I am concerned that, over time, it could develop into something. I may make an appointment with a sports specialist, because I also have developed some mild pain in my right hip, which I think oddly is related to the fact that my left leg is slightly longer than my right one (I mean, you can't tell just by looking, and I haven't actually measured it, but I can tell from my jog, and how my gait compensates when I am trying to keep time with my workout music).
