Why would there be swelling along my back and front of my shoulder blades and down the center of my back along each side of my spine. sometimes, the front of my shoulder blades swell and also swelling in my shoulders and up neck.
Swelling is caused by excess fluid in the tissues and can be an indication of imflammation, injury or infection. You need to see your doctor. There is no way to tell what is causing your swelling without a medical exam.
Good luck to you.
