Just a few thoughts on the past couple pages of posts:
***Regarding how surfaces affect the loss of coordination... I saw a manual therapist that explained to me that my left problematic leg is hitting the ground very hard in the heel and causing my femur to jam into my hip harder than it should/does on the right. This further aggravates the sciatic due to the additional pressure from the piriformis trying to control the extra jamming my hip is getting from each left foot plant. Why is my left heel hitting the ground so hard? Well, my sciatic is damaged to begin with and the nerve signal gets weaker the farther down the leg you go, especially comprising the muscles necessary for dorsal flexion down in the foot. Rather than being able to control a strong, smooth foot plant and toe off, I'm unable to control those muscles and thus hit the ground harder than on the right. SOOOO, the harder the surface, the harder my heel hits cause there's less "give" to the surface I'm running on. Grass has more give than a track; dirt trail had more give than the road. Anyway, just what this guy thought about it...
*My left leg is the problematic leg and it is the SHORTER leg. My problem leg is not the longer leg, as it is for some of you. Had a CT scan and my "good" right leg is the longer leg by 5/16". So, I use an insert on the left.
*My PRs are quite old now as I haven't been able to race properly since 2001. Certainly not bragging as I realize there are thousands of people in every country around the globe better than me, but my best 10,000m was ranked 25th among American women in 2001 by T&FN. I was all hopeful to get to work and get even faster after college and move on to the marathon, but, started getting my loss of coordination in Sept. 2001 and couldn't get back on the track, let alone move up in distance to the roads. I have yet to competitively race anything other than cross country since college when my leg was good. Which, *sigh* is becoming longer and longer ago...
***Hmm... cell phone in the pocket? That's similar to all the articles on men getting sciatica in the same leg that they keep their wallet in and sit at a desk all day at work or driving. Probably more from pressure of the item under your butt cheek rather than any sort of cancerous/radioactive signal being emitted... But, haven't really done any research on this to back up my initial opinion.
***Potassium citrate. Definitely gonna try it and will report. My dad died of kidney problems (specifically, glomerular nephritis) at a young 42. I remember him always eating bananas and drinking gatorade cause the docs told him he was potassium deficient. I always crave salt (ie: in the summer I add 1/4teaspoon to my 32ounce gatorade!!!) and wondered if my body was looking for a replacement for potassium it wasn't getting??? So, not being a hypochondriac, but just curious about any possible connection, googled some stuff on "kidneys potassium salt loss of coordination" a few years back. Didn't figure anything out, so am really glad to get your idea and explanation. Even if I personally think a needle nicked my sciatic and caused my problem, I'm willing to consider the problem actually could just be the pH of my blood being off and try a new vitamin to correct the problem...
We've gotta hang in there--- we WILL figure this out!!!
