Tests, round one....
Feb. 21st, 2005 05:02 pmWent for NCV[1] and EMG[2] tests today. Results were... inconclusive, I think. IANAD, but essentially:
Not tarsal tunnel syndrome. Probable tarsal tunnel inflammation. Definite loss of S1 nerve (dexter), but I knew that already (unrelated[3] pre-existing back injury).
The not tarsal tunnel syndrome result is a good thing, in that if we get the problem fixed it won't come back. (Unless I do whatever triggered it again.)
The loss of the S1 makes diagnosis a bit harder, as the S1 is down the outside of the ankle to the outside of the top of the foot, and is kind of intertwined with the lateral nerve on the bottom of the foot (which is the one causing all the trouble). Any nerve test must be done with care to make sure they're not measuring an essentially dead nerve.
MRI on Wednesday, followup with ortho next week.

[1] Nerve Conductance Velocity. Sensor at one end of nerve, apply electrical stimulation to other end. What they don't tell you in the info sheets is that they ramp up the stim until the muscle jerks.
[2] ElectroMyoGraphy. Tiny needle with sensor attached poked into muscle. Move muscle, sensor detects electrical impulses. Audibly. Do you have any idea how hard it is to relax a muscle in your foot when there's a needle stuck in it, and there's a speaker buzzing?
[3] unrelated, to the extent that it wasn't caused by the foot problem, but it may be an underlying cause.
