I am going through that right now and it scares me too. I had my doctor test me for rheumatoid arthiritis again. Im gonna suggest an mri for my own piece of mind to make sure nothing else is going on.

Yes ive had this symptom since i can remember. Not painful but generally loud & i do find relief when stretching (turning to side) my back & it cracks. I just ordered plant/food based all natural non gmo multi-vitamin & a fish oil too i cant give feedback as i haven't started them yet but im hopeful that i will find relief... Your diet can influence your fibro a lot

Yes but you shouldnt worry until it feels and sounds like grinding with sharp pain. Mines always popped and clicked very audibly but my arthritis spread quickly and now my joints grind. When i do too much they also swell. Its agony so just take care and be vigilant.

I asked my physical therapist about this and he assured me it was mormal.

Yeah its a completely normal thing for me. Especially hips and shoulders. Even my spine pops whenever I move a certain way
