Sounds like a gall bladder attack...especially if it is radiating into your back on the right side , eat low or no fat meals , don't eat after about 5pm ..there are foods that will trigger an attack that you should avoid, if you go to yahoo you can get a list of them .If its very painful a visit to the doctor as it could be gall stones ..good luck
Hi, You have probably pulled a muscle but just to make sure i would check with a doctor. If it gets worse i would go to your local hospital. Never feel silly about asking for help with your health at the doctors. Good luck hope you are already feeling better. Take care
