So, in the last month or two I've been doing more upper body strength training with weights. I'm not sure if I'm just being paranoid about hurting myself, but I feel like I've noticed my shoulders popping a lot more. It could totally be that I'm more aware of my body and thus just noticing everything more! My hips also make popping sounds and to a lesser extent some other parts of my body do the same.

It never hurts, although it's definitely weird/a little uncomfortable at times (eg during lateral raises). My joints may not pop/crack on every rep and they definitely do it outside of exercise too (eg when I'm washing my hair). I've paid close attention to form and I think I'm doing the exercises correctly. I took a week off from upper body workouts and took motrin several times a day to see if it was related to inflammation, but no change. I've read online that if it doesn't hurt then not to worry, but I guess I'm looking for reassurance from others that I'm not the only one?
