I have read other postings and replies concerning nerve studies and especially EMG tests. My neurosurgeon wants me to have an upper body EMG test of my shoulders and arms. I am really looking forward to having the test done and hope to get as much helpful information as possible. People seem to suggest that there is nothing (for example: medications, supplements or pain treatments) that can interfere or cause an inaccurate result. I had two cervical ablations done last year and a large epidural cortisone injection last month. My pain management doctor has also prescribed large daily doses of Gabapentin, Propanalol, Flexeril, and Lidocaine patches. I also use cold packs to help with the pain. Some forum participants have suggested there is no pain management treatment or medications that will effect the test results and to just continue with the treatments and medications. While I have also read that EMG tests can be “subjective” and are not always accurate, **It seems to defy common sense that the ablations, epidural injections, and nerve and pain medication would not have any impact on the nerve study including the EMG? I know virtually every person’s situation is different, but could you please reply to this question and share your own experiences and insights with nerve testing? I want to do everything I can to make sure the tests result in useable data for my neurosurgeon. Thank you.
