Hi, My Girlfriend Has Sever Pain In The Back Of

Hi, my girlfriend has sever pain in the back of her left trapezoid (?), the upper back part of her shoulder, that gets a little relief when she reaches over with her right hand and applies pressure on the spot that hurts. She has been under a lot of pressure in the last month with work, family, etc. She uses a chiropractor occasionally, and did last week to try and help with the pain, but tonight she is tears. She is going to try and make it through until morning with a heating pad, which helps a little. She's also trying deep breathing techniques and to mentally relax her body. Any ideas or suggestions?
