back pain under right shoulder blade

what can cause pain under the right shoulder blade radiating to the right side?
Ive had my kidneys x rayed and an ultrasound performed but no answer to whats causing the pain. It goes around to the front. Around the liver area. I also have pain under my breast bone that comes and goes.
I have a genetic liver disease that my twin sister needed a transplant for. My liver problem is regenerating itself.
And I have the feeling of a tight chest and throat
Your liver can be enlarged. Do you drink a lot of alcohol? You could have cirrhosis? Pancreatitis is another option. I didn’t pay attention if you’re make or female before I answered the question, but if you happen to be female and pregnant, this is a very serious complaint that can be a sign of pre-eclampsia… that needs to be checked immediately. Regardless, it sounds like a liver problem.
