I have herniated discs at c4-c5-c6-c7, lightly touching the cord, but with no high signal on MRI. I have pain and tingling in legs, arms and scapula, with some little weakness sometimes (legs). But I do not have long track sings: no hyperreflexia, no Hoffman, no inverted supinator sign, no imbalance (no positive Romberg test), no numbness, no vibration or lost sensation. Is the symptomatology compatible with cervical herniated discs, as myelopathy? Should other causes be investigated?
Generally, without signal change in the cord, but with some effacement (touching) of the cord without real compression and no long tract signs, it would be highly unusual to be myelopathy. There are many other disorders that can cause extremity tingling such as peripheral neuropathy or some other metabolic disorders.
