Recently, I started having sharp pains in my tricep (at least it's on the underside of my arm) near my armpit whenever I do a pulling movement. This includes pull ups, weighted rows, etc. The pain happens when I flex my bicep, so I'm assuming it is stretching my tricep out beyond a comfortable range of motion. I've never had issues with pull ups or rows before (I've considered myself quite competent - RC/PE7 until now). All of the sudden this pain has come on.
In addition, when I flex my bicep and internally rotate it, I get a dull pain in my forearm near what I'm assuming is the bicep tendon (flexion and rotation...?).
To top it all off, my left shoulder has an impingement, which I am currently doing rehab for.
My questions are: does the impingement have anything to do with the pain I'm feeling in my arm (I wouldn't think it should), and does anyone have an idea of what's going on with the muscles in my arm? I don't have a lot of knowledge of anatomy, other than I know this isn't normal and it's preventing me from continuing with any RC progression (I can't even scale back to any of the earlier progressions).
If anybody has an idea of what's going on, and some ideas of rehab and stretching to fix it, I would be very appreciative.
Thanks,
Ryan
