Having proudly finished C2 5K three weeks ago, with a 4.8K run. I was so looking forward to more running this summer and certainly nailing 5K in 30 mins. Sadly the very first post grad run and my first real injury struck. Pain in left heel, up to the ankle especially on the inside. Maybe Achilles problem? Seems to be a pattern: Walk/Running is OK at gentle speed for 20 or 30mins, then pain starts after I run and by next day I am limping, hurts walking when I extend right leg beyond left, and when I go downstairs. After 4 days it is completely gone, but the minute I walk/run the cycle starts again. How can I get rid of it long term? Do I need to do stretches for weeks or months before I run again? Heard heel pads can help. So annoyed. Losing all that good I put in to the program. Help!
