I've had small stints of weightlifting my entire life, but recently I've tried to get more serious about it. I started taking supplements, I added more routines, I started following recommended lift patterns (5 day split), but about 4 days ago my shoulders started popping when I lift my arms (while just doing normal things with nothing in-hand) and it's disturbing me.
Both shoulders do it, but the right one does it much more readily and frequently. I wouldn't say there is true pain when it pops, but there is a small amount of discomfort (it's possible it's just mental discomfort at the idea of it though, I'm not positive).
The upper body lifts I do are: weighted pushups, chest dumbbell flies, pull ups (with various grips), standing curls, over-the-head tricep lift (one dumbbell), dumbbell laterals, and military press (dumbbells).
The possible culprits: I read that doing military press behind the head can cause problems, so I did switch to trying to do them in front of my head, but I had been doing them a few weeks above/behind the head before reading that. Also, I don't have a bench so I do the chest flies on the floor which causes my shoulder to pop sometimes because of the pressure against the floor. Also the last time I did laterals my shoulder was popping as I came up. (I might go too high with my laterals?). But who knows maybe it's the over-the-head triceps or the pushups that are doing it. I have no idea.
I stopped lifting all together when it started happening 4 days ago to see if it would heal/fix. I also started taking ibuprofen to help with inflammation and tried to make sure i was sleeping with my arms at my sides instead of above my head in case it was the way I was sleeping. But it's still popping.
Does anyone have any tips on how I can either fix my shoulder or make sure the exercises I'm doing aren't making it worse? Really don't want arthritis later in life...
