At least I think that is the cause. I use my left hand, and it's the left shoulder that's painful. The pain shoots down into my arm and up my neck. Got it after I began vaping on a mechanical mod with a 18650. It's not as heavy as my Ismoke VTR, but I didn't have any pain when using that one. I don't chain vape, but I vape very much.
I hold the mod with my finger tips. Can that be the cause?
