Been to doctors again ! . Thought I was on the mend sat . Was walking slowly & virtual pain free , yesterday back to square one , it was swollen & couldn't walk down stairs . Off I hobbled to the doctors , he's referred me to a physio 14th jan . Its a sports injury clinic & it's just across road from where I live , so hopefully I should get to the bottom of this . He said it's bio chemical injury to the soft tissue & can be as bad as a fracture or break .
