Re: How do you know if you have permanant nerve damage and how does it happen?
mostly,you kind of rely on certain symptoms such as numbess or tingling or pain or what are called "parasthesias"(bizarre sensations or feelings of something happening to your body?). then having an EMG would actually show whether or not the nerve flow to/thru any nerve is affected or being impeded by actual damage or something that is somehow impinging or compressing a nerve to the point where the flow impairment shows with changes in the velocity. thats about the only thing an EMG really can do,find solid nerve flow impairment. it wont show intermittant/posistional typs of impingment tho unless the nerve itself is being impinged at the time of the test.
nerve damage itself can happen in just about any type of actual injury/surgery,it all depends on what areas get affected. then there is good old spinal damage/deterioration that can impinge or compress any given spinal nerve too. disease processes can also damage nerves as well. neuropathic types of conditions are also indicators of real nerve damage/loss too. as in peripheral/diabetic neuropathy. then there is of course actual spinal cord damage/injury that can damage a ton of different nerves and nervous systems too,only it occurs mostly all at the very same time since it is IN/on the cord itself.
anything that simply can damage a nerve such as the above,will show itself in some level of symptoms. anything that is actually governed by any given nerve will be definetly affected in some ways. does that help at all? marcia
