Severe back pain

I have experienced back pain for quite some time especially in my right shoulder and lower back region.  More recently I have had a severe pinching pain in the lower medial side of my right scapular region.  The pain is constant but worstens when I work (as a bartender) but is the absoute worst when I am sitting in class, relaxed taking notes.  There is no way I can stretch or position myself to ease the pain.  I have heard this could be a pinched nerve, herniated disc, or be a consequence of my somewhat large breast size.  What is it??

The symptoms of right shoulder pain that is constant whether you are active or relaxed may indicate disc problems within your cervical spine.  The possibility of a disc protrusion or herniation or other degenerative changes could be causing irritation or compression of the spinal nerve root (ie pinched nerve).
The only way to verify if this is the cause of your pain is to have cervical spine x-rays to see if there are structural changes and an MRI to determine the nature and extent of any nerve involvement.  It would be beneficial to make an appt with your primary care physician for a medical evaluation and appropriate diagnostic tests.
Your breast size could be a contributing factor as well, but the disc problem would be the primary cause of your symptoms.
Post with an update and any additional questions/concerns you may have.
