I've succumbed to the dreaded shin splints. Haven't been out for a run in 11 days as they're still sore (they only hurt when I go up and down stairs now, not when I walk). Had thought for a while that my running shoes weren't supporting me properly so have finally had gait tested and all that, have a shiny lovely new pair of trainers to try out, tried a run around the block this morning and the shins hurt like hell. I'm so frustrated as all I want to do is get out and run. Has anyone got any advice? How long until they feel better?
