(female- late 20s) At first I decided to take it easy and run less, but after a few weeks I wanted to get back
more frequently. I was able to push through some of the pain
with hydration, stretching and breathing techniques. However, it's been 9 months of this and I don't see much improvement. I've visited the doctor and she said it was likely just intercostal muscle cramps. I've been doing physical therapy, but the ache has persisted.
