My friend a gal aged 22 years having frequent problem of having pain in arms and legs, health normal, what are the cause and remedy?

Needs to be checked : Pain in arms and legs all the time needs to be checked by your doctor . She is only 22 years old and having frequent pains in both arms and legs. She should make an appointment with family doctor. Will need detailed history past and present and comprehensive medical examination. And if indicated may need blood and urine test and may be other tests to find out the cause and appropriate treatment .
