Muscle pain as previous reported at base of spine both sides. I have a feeling as i mentioned before that this simply my backing saying you're too heavy and you don't use us enough. So for some advice from our resident physio's. Should i race sunday and if so what measures can i take ?. Massage ?. Big cummerbund style bandage to support it ?. Some tiger balm type stuff ?. O just not run hard until enough weight lost and carry on with pilates.
