I have pain in back right hand side behind shoulder blades, abdominal discomfort and bloating, nauseus and dizzy spells excessive foul windk?

Shoulder & abd pain. While no precise diagnosis can be made based on this description some causes to think about are gallbladder attacks which can cause nausea, right-sided abdominal pain that radiates to the back around the shoulder blades. This fits this description the best. Other diagnoses to consider would be pleurisy, peptic ulcer, severe constipation, severe acid reflux or gastritis.
Pain. Check out your gallbladder. Shoulder pain could be a sign oh gallstones or gallbladder inflammation.
