Loss of control in the right leg only while running
by Larry Kerr

I suffer from, for lack of a better phrase, loss of control of the right leg, but only while running. There is no pain, no cramping, no spasms, and no tingling. This only occurs during distance running and only in the right leg.
The leg basically quits working properly and forces me to land well back on my heel. I get no push-off on that leg, forcing my left leg to do the majority of the work and irritating the left hip flexor. Running becomes much harder because I'm using one leg.
If I stop and walk a bit, I can resume running, but only for a limited time.
I have had an MRI and EMG. The MRI shows bulging disk at L4 and L5, but the conclusion was that they are not bulging severely enough to cause the problem, especially when there is no accompanying pain.
The EMG showed a nerve in the right leg is being affected, but not the source.
No other activities are affected, including lifting weights and walking.
There's something going on, Larry, but it's going to take a careful and thorough examination to figure it out.
I would agree with your doc about the MRI. The L4-L5 disc wouldn't affect your toe-off on your leg. That's the gastroc - soleus muscle complex, mainly S1.
I wonder if that irritation in your thigh isn't an important clue. It's points to something high in the lumbar spine, or perhaps the sacro-iliac, or the hip. No groin pain or stiffness? Can you pull your knee to your chest and rotate the hip, equally both sides?
Do the "Slump test" that you'll find at Chiropractic Help, and ask your chiro to do the Femoral nerve stretch test. Can't do it at home.
Keep looking, keep thinking. There's a basis to it. A FICS trained chiro would be a good idea.
Let me know who finds out what the problem is. Interesting.
