Everytime I do an exercise that involves raising my legs my hips pop. Idk if I should go to the chiropractor, it doesn't hurt just annoying.
I noticed that with hips as well as with knees already. Maybe something's not exactly the way it should be, but it seldom is (like as almost nobody has a perfectly straight spine).
For my case I talked to some doctors as well as physical therapists and they said there's no need to worry about that. I'd suggest, as long as it does not hurt whatsoever, to keep it under observation for a couple of days/weeks and to go for a professional if you notice any change - or if you feel unsecure about this.
For myself I accepted my body to make weird noises for being normal coming at age ;-)
My hips used to do that until I started strengthening my hip flexors. Use the workout "free your hips" and you'll slowly notice a difference. Now mine don't pop any more.
You should consult your physician.
I have more of a click sound rather than a popping noise. I think it is just my bones acclimatising to the exercise and stretching. Best of luck with the workouts. M.
I have the same thing and my massage therapist doesn't seem concerned about it. For me it's not the popping/cracking sound as much as the feeling that something's jammed in my lower back or hip that feels uncomfortable.
