Hello, my boyfriend is 20 years old; and is having pain in his right hip socket. In the past he has popped his hip back into place because of uncomfortable cramping..."feeling weird" But now, for the past two weeks, he has been having the feeling of his hip popping out of place or joint? Feeling like it may come out of place??? What could this be? He says he has never really injured it or anything... What can he do for this particular problem? Exercises or stretching? Vitamins? Please let me know if there is anything I can recommend for him to do.
