Four stretches
1. Sitting with affected foot over other knee, push top of foot and toes forward until you feel outside of calf and hold for 20 secs.
2. Normal calf stretch holding wall
3. Still holding walll bring back (affected) foot so toe is in line with heel of front (good) football and go down using your knees
4. Affected foot in to wall toe up and push in to wall, feeling the back of the calf stretch, agonisingly in my case.
****. I don't do any of them. Will get on to it. Was a bit confused how to use the football in exercise 3 but worked out foot eventually. Thanks.
