Pain in arm from bad form?

[gettingthere]

Hi Cathe and educated crowd!

The last few months I've been experiencing some pain in the outside part of my arm where the shoulder meets the bicep (or tricep? can't decide) I can't figure out which exercise I must be doing wrong to have this happen. Any ideas?

Thanks,
Liz

I noticed that I had the arm soreness similar like yours, but including most of arms and sides of my torso after I did Kickboxing in CTX and Kick Max. I would like to know if my forms are not right or it just Kickboxing used muscles that weren't trained in Upper Body.
