My EMG also came back negative...twice! I started having wrist pain back in 2004 so I was referred to a hand/wrist specialist. He couldn't figure out what was wrong after all the tests came back negative but thought I might have a cyst on my wrist, so he scheduled exploratory surgery. Guess what he found when he got in there? Nothing. He closed me up and continued to scratch his head about it, so I sought a second opinion. The second orthopedic surgeon had a diagnosis of Cubital Tunnel Syndrome for me within the first 10 minutes of the first exam, so I was initially excited. Given that this diagnosis meant a work-place injury had occured (previous 7 years were spent typing 8-10 hrs/day with few breaks), the case was taken from my insurance and turned over to Worker's Comp. This doc did another round of nerve conduction tests, but they too came back as unremarkable, so he sent me to a round of OT. The Occupational Therapy yielded few results. During the next (and final) office visit, the doc told me that there was not yet enough nerve damage, so he was not willing to do any surgeries yet. Frustrated, but resigned to live with the pain, I dropped the issue. Then, after the birth of my daughter in 2007, my symptoms began getting progressively worse, so I called the doc's office to make an appt. I was told that I would have to pay for any exams or tests out-of-pocket, as my Worker's Comp claim had been shut down. Turns out that the Comp rep had forced the doc to rate me at "maximum medical improvement," so he could close out the case. This effectively rendered me unable to receive any further treatment for the disorder. Now, 4 years after that first pain, my symptoms are ever-present. I would be willing to bet that if another EMG were done on me today, it would yield positive results. I won't know, however, unless I hire an attorney or pay out-of-pocket. It's an unfortunate trend that many specialists refuse to do surgery on a patient who presents with negative EMG results. If I were you, I would emphasize to your doc that a negative EMG does not mean you don't have CuTS, and that waiting could possibly do irreversible damage.

P.S. If anyone has any ideas on how to get treatment without having to spend thousands in a case like mine, please share.
