This just started last week. I feel a slight, but not too harsh, pain on the inside of my arm near armpit when i do bench press and even sometimes on lat pull downs. It doesn't hurt as bad when i do incline bench though. I can work through it, but just uncomfortable. I just started a cycle, so i wanna figure this out and try to get things back to normal fast. I'm taking a couple days off and rest it for now. Anyone know what this could be?
