Hi,
Based on the history you provided I feel this should be related to nerve entrapment anywhere in it's course. Usually there are two places - one at the
intervertebral disc region at
cervical spine and other due to trapezius
muscle inflammation.
The pain you mentioned sounds like radiating in nature. that means it's definitely a nerve pathology involved here. I think may be you have taken the MRI of cervical spine? is that so? Did the MRI reveal anything nerve entrapment in the cervical region? Or you took an MRI of shoulder? Well we need to know this because arthritis can be diagnosed in shoulder but not in the cervical spine usually.
Also, may be you have undergone some
physical therapy like - TENS therapy and
ultrasound therapy? is that so? did it help in you in anyway like 20-30%? What where the application location? the shoulder, arm, or cervical region? Lot of things you missed to mention in the history but that is okay. I want to know if you are diabetic and having any
high blood pressure symptoms? Your age too?
Now with the solution part I would like to advice you to workout for a particular group of muscles like the neck, the Trapezius, the interscapular muscles , the shoulder girdle muscles. Hope this muscle groups strengthening helps you get rid of the pain as in my clinical practice I do find people getting benefited with proper diagnosis and treatment plan.
Hope I have answered your query. Let me know if I can assist you further.
