I'm confused about nerve conduction studies-- I've recently had one on my neck and shoulder muscles to help determine the cause of a two year long pain syndrome. ( i am a no longer practicing dentist) On the one hand, I was told that these studies can detect nerve root impingement or decreased innervation to muscles before the patient even realizes there is something wrong-- the tests are apparently that sensitive.
On the other hand, I was also told muscle spasm and pain could indeed be from entrapped nerves (or nerve roots) that slip under the detectability of these tests. so, what's the real deal??
Will issues that are strictly myofascial show up on these tests???
Could a nerve root still require surgical intervention even if this test was negative for a radiculopathy?? ie, can someone get pain from a nerve root impingement and still have a negative test??
I had nerve root blocks that seemed to be diagnostic, but if the problem(s)were distal to the block (ie in the neck musculature for instance) wouldn't these blocks be positive even though the entrapment (or myofascitis) is not of the root itself??
I had both my shoulders scoped, and I had a c5/6 c6/7 minimally invasive foraminotomies--- no help. sorry for so many questions. I'm just trying to get the facts straight.
Symptoms are pain/tightness -- sometimes into chest muscles/always in neck, posterior shoulders and sometimes anterior shoulders. Some relief w/ stretching.
Thanx again,
