blimey !!! ive had mine 6 months , but can see it going on probly tilll 2009 . hoping to run again by april , but if i have pain i wont bother. my next step is nhs custom orhotics , although nhs physio said superfeet green were ideal for my gait . not going to risk running as ive got some walking holidays in the summer and i dont want to mess these up . refuse to pay a physio , would sooner take up cycling than pay out lots of money .what does shockwave therapy involve ? also heard there is a last resort operation ?
