OP, please don't follow this advice until you know exactly what your injury is. You could make it worse if you blindly follow this advice.Get a tennis ball. Put it on the ground and sit on it, with the tennis ball effectively massaging your injured area... roll yourself over it until you find the point of unbearable pain... and hold it for about 20 seconds![]()

I paid £350 for 20 weeks but I suppose if you're looking at specialised running coaching they may be more expensive.
