Seven months ago I was running upstairs, skipping every other step for exercise, when what I thought to be my sciatic nerve in my left leg 'fired off' with what I can only liken to a huge shock. Thought it a fluke, waited 10 minutes, resumed stairs, and the same thing happened. Ever since, I'm unable to walk briskly without setting it off, and some days the nerve's so twitchy, I move sloth slow and still can't trust a single step. I sometimes get a smaller, 'warning' sensation; other times, even the slightest forward bend at waist or moving leg to side or forward will send a huge 'wave' followed by two more "waves" of unnerving, debilitating sensation.
I have no control over my leg when it's intense. Sometimes it feels as if the floor has raised 18 inches. The sensation now seems to originate from the front of my left hip joint rather than the sciatic nerve, as I'd first thought. It overwhelms my entire leg and occasionally shoots up into my lower abdomen and lower back.
MRI shows some lumbar narrowing and disc disease (I'm 47, female), but isn't impressive, I'm told. I used to bike, hike, enjoy quick paced walks. Now I fall without warning. MRI of head ruled out MS a few years ago (when I had left side neuro symptoms with my arm, hand; had a large bulging disc and cervical fusion--C4-C5. Hand and arm still feel 'asleep' but post op., symptoms in shoulder never recurred).
The doctors seem nonplussed. I'd be tremendously grateful to hear that I'm not the only one whose ever experienced this, or for any suggestions.
