pain in my upper right abdomen and back. First time for around six months. Went away for about six months and returned and has hurt for 5 months.?

Other symptoms? Does it feel like a pulled muscle? How long does it last ? Do certain foods make it worse. Have you tried any meds? Did you injure the muscle working out? Would you say it is more related to food or activity? If food, you may want to obtain us of gallbladder to rule out stones a common cause of rt abdo and back pain exacerbated by food. Is there any abdominal pain? Bloating? Nausea?
