I was taught in school that the popping was caused by the synovial fluid in the joints. However, if this is painful or continues to concern you, you should probably talk to your doctor about it.
yes it does sometimes...im also feeling like something getting stuck or misplaced(i just feel that way...dont know its just my feeling of it is really)i try to turn or rotate or move the part (arm, leg, hip, shoulder)so that i get to normal..im really getting worried and confused as its getting worse day by day....can you please help and tell me what exactly is happening with me??
Thanks!!
Does it hurt when it pops or crackles? If you feel pain I would see a doctor.
