Yes, I ignored symptoms years ago and ended up with a stress fracture, and then when that got better, knee problems (probably from all the limping creating a muscle imbalance).
Now I'm really aggressive with treatment like ice, ibuprofen gel (no idea if it works) and foam (nobbly one) roller on my calves and hamstrings at the slightest hint of pain or tenderness. Seems to keep me out of trouble, though the thing that seems to make it flare up is probably too much tarmac slapping with the wrong or worn out footwear and overstriding, particularly when tired and losing form.
