Hi Jeanie
The calcaneal nerve is one of the nerves that i have that is entraped,,I had 2 eeg's done and 2 emg 's done,,Both Drs who performed them both told me that since the entrapment is near the end of the nerve[ bottom backside of heel] where it ends,,that the test will come back normal,,both drs' Both said this before administrating the test.They implied that the entrapment had to be before the nerve ended to show up,,,,And sadly , they were right,,both tests were normal,,but both Dr's and the podiatrist DR proved the entrapment by the signature signs which included tapping on the back of the heel where the cut had healed up, and it sent tingling,shocking sensations and pain thru the foot and radiating up the leg,,Another symptom was when i would soak in a hot bath,,the back of the heel would have an electric sensation , like a 9v battery was on it,,I too ,as yourself would welcome the surgery,
