If the MRI is clear, and nothing shows up, you may have an irritation of the brachial plexus. Someone who knows how to deal with trigger points would be the solution if this is the case.
When patients have this type of pain, there are very sore spots in the sides of the neck above and below C6, as well as at the area of your pec minor muscle, beneath your clavicle.
The pain is worse around where the c6 is but can radiate up the spine and out across shoulders. Sometimes I have some sensations from my armpit to the elbow. But my main problems is a sometimes extremely dull ache that leads to a sharp pain in my neck. I have an mri scheduled for tomorrow so maybe this will help to find out what is causing this. Thanks for your reply.
What type of pain are you experiencing... can you describe it for me?
