The FMS pain is often accompanied by stiffness. possibly can make pop noice more.
Accoring to your symptom,It sound some inflammated tissue around your facet joint.they can lead to both pop and pain.
Take care!
What is a facet joint? and is their anything I can take to strengthen my joints so that they don't pop so often? My hips pop on a daily basis at least 5 times a day, me knees back and neck are not so bad. If the tissue is inflamed wouldn't a NSAID help me, because it does not help much, also I have ulcers I cannot take much medication. Pain relievers make my stomach upset, all I take is natural supplements for FMS.
