On Friday I sat on the loo (as we all do!) and when I got up had a spasm in the lower back. I was walking like a very old man...you know bent over...it lasted through Saturday..into Sunday...stopped me running today. I know we are not a medical forum but again this is prob an injury that most of us had had at sometime or other. The funny thing is cycling does not seem to make worse. I am taking ibuprofen and rubbing deap heat into the area but the question is how can just "getting up" cause such a painful muscle spasm. I hope that tomorrow it will be on the way out...
I used to suffer badly with running, then I heard about the barefoot technique,it made an instant difference.
I went for a run on my Puma trail shoes, had to bail, due to back pain, knee pain after about a mile, I bought a pair of Vivobarefoot trail shoes which arrived the next day, went for a run, ran twice the distance, without stopping, no back pain, have used this technique ever since, it does take some time to transition, as the calf muscles take the strain, not the heel and shoes, I find it more efficient, there are many shoes out on the market,
Nike do plenty, my Kuga Zoom trail shoes are chunky, but quite flat, cushioned, but not much of a wedge, good for mid foot to forefoot running, larger toeboxes also help those with wider feet, NB do a minimal range, but some of those are like wearing socks! ( they are great for flying as they are so comfortable)
I don't do a great deal of running, I prefer to cycle, but the minimal and flatter barefoot shoes have also helped with walking, where I used to suffer with back pain even then, might be worth looking into
