Any medics out there? Started running 3 months ago, now up to 1.5 miles 3x a week which I complete in around 16 minutes. Aged 44, non-smoker, about one stone overweight, safe-limit but enthusiastic wine-drinker, controlled asthmatic with IBS! Are you beginning to wish you weren't reading this? On most runs, within two minutes of starting, my left leg begins to feel numb. Sometimes it's the calf, sometimes the thigh, but it feels like dragging something dead along with me! When my thigh is affected it feels sore for the rest of the day. Rest makes no difference, and it comes and goes with no apparent logic. No visible sign of a problem. Does it matter, or should I stop being such a baby and looking for a reason to stop running, and get on with it? Thanx for reading this.
