Your husband’s presentation is commonly associated with a cervical disc herniation. Pain typically starts next to or behind a shoulder blade and some time after develops in the arm.
Apparently, your husband cannot have an MRI due to this BB but I would still check with a knowledgable radiologist to see if an MRI can be performed. I do not recommend any specific names on this website but if you call the office at our 888 number, I can give you the name and contact information of a respected radiologist who can give you more information.
You husband received a steroid injection into the suspected painful shoulder. I assume that a numbing agent (lidocaine) was also injected at the same time. If so and assuming the injection was placed in the correct compartment, this was an opportunity to find out if the shoulder played some role in generation of pain. For the first three hours after the injection, did the pain in the shoulder and arm significantly diminish? If so, did all the pain subside or only a portion of the pain. See “pain diary” on this website to understand how to report these findings.
C6 foraminal stenosis is well described under “Conditions”/”Neck-Cervical”/”Radiculopathy-pinched nerve”. This is a condition where bone spurs fill the exit hole of the nerve causing a pinch of the nerve. This condition is possible but I would suspect a herniated disc causing the problem (see same section under herniated disc). The symptoms would be the same but a herniated disc is harder to see on a CT myelogram and is sometimes missed.
It would not hurt to gain a second opinion if you don’t have enough information.
