What could be the cause of shoulder pain, which makes it difficult to life the arm repeatedly? The person experiencing pain has not met with any accident or hit anything, only the previous day, she carried very heavy items. Does carrying heavy items cause delayed damage to the shoulder? Is there any way to prevent this shoulder pain problem in the future ?
