I am not sure what you have tried to resolve your pain but a typical treatment involves a systematic approach to find the potential sources. Chronic pain is usually related to microtauma caused by repetitive movements or postural strain. So, take a look at the things you do and the postures that you maintain.
The textbook will say that the traps elevate the shoulder girdle. This is a typical stress related posture to assume, as well as the position most people will adopt behind a steering wheel or at a computer desk. So with that being said we may need to work on stress relieving practices as well as adopting new shapes that you hold your body in. I know from clients in the past, one biggie is trying to reduce your number of pillows that you use. Ideally, you only want enough to support the curvature in your upper neck area.
Anyways, as far as treatment goes. Once you have determined the areas of pain, you can follow these tolerable steps:
1.epsom salt bath
3.foam rolling associated areas
hope this helps,
