Dr. Corenman,
I had R rotator cuff repair with biceps tenotomy in June 2016. Despite scrupulous adherence to OT rehab program, I developed adhesive capsulitis, which resolved after manipulation under anesthesia in November 2016. Pain continued, and a subsequent MRI showed an anchor was detached (and likely was never attached). A different surgeon successfully re-repaired the rotator cuff in February of this year.
Therapy progressed quite well until the 11th week, when we began very gentle strengthening during my OT session. Within hours I developed painful radiculopathy in the right arm, triggered by looking down (such as when reading or writing). Pain radiated through the triceps elbow; it was mostly ulnar, with right hand weakness and numbness in 4th and 5th fingers.
MRI showed DDD, possible C5, 6, 7 impingement. (I am 62 y.o. female.)
Spine surgeon ordered traction, which we tried twice. It caused immediate severe headache and dangerous spike in BP. Subsequent carotid ultrasound showed tortuosity in the L dorsal extracranial vertebral artery, so traction was discontinued. PT exercises (isometrics, stretches) are marginally helpful, but PT manipulation probably made things worse (tingling scalp, vertigo, increased neck pain), so PT for neck was discontinued. (I remain in OT for shoulder.)
Nine days ago, I had a C7 nerve root injection by an experienced pain management anesthesiologist. The numbing agent did not relieve the radiculopathy (not surprisingly, as my symptoms were more consistent with C8 impingement). Unfortunately, I now have symptoms of C7 radiculopathy, too, which seems to be the result of the injection. The nerve feels inflamed and irritated, with sharp pain through my hand and to the end of my 3rd finger.
My question is whether to try another nerve root injection at a different site, given the increased sensitivity of the nerve that was injected. My shoulder surgeon is concerned that the neck issue is interfering with rotator cuff rehab, because I am not gaining strength as expected. So he wants it resolved. The neck specialist is likely to want to try another nerve root injection, but I really don’t want another nerve to be as messed up as this recently-injected one is. (I am mildly allergic to the dye, but diphenhydramine relieves those symptoms.)
How likely is it that another nerve root injection, in a different nerve, would be harmful to that nerve, given this history?
Thank you for your time.
Well, your SNRB did not give you relief which helps to rule out the C7 nerve (as long as the block was performed properly). Your MRI does not note any C8 nerve involvement (the C7-T1 level is not implicated). The other possibilities are that you have thoracic outlet syndrome or the shoulder is causing pain. You could consider an intraarticular shoulder block. If you gained great relief from this injection, you would have an obvious pain source and it would not be the neck. A simple physical exam test could indicate the presence of thoracic outlet syndrome.
