I'm having pain in my right shoulder blade, a bit in the right side of my chest too. No pain in abdomen but having burping. Gallbladder?

Possibly! You are right, gallbladder pain can sometimes be felt in the right shoulder blade or side. But other things can cause pain there. If it hurts when you breathe in, you should see a doctor right away to rule out a blood clot to your lungs. Pleurisy (inflammation of the lung lining), muscle strain, fluid around the lung, and even problems with the esophagus, liver, or pancreas can cause this.
