I have been having some aching around my achilles tendon for the past few days. I kept running, but today I skipped a timed run because I didn't think it would be a good idea. After hearing some horror stories about achilles tendonitis, I was wondering if anyone knows what this is. It hurts to stretch, and it doesn't really hurt that much while running, but I know it's there. It's not just on the tendon, it's spread around my ankle and the side of my foot sometimes too. I thought it would fade away, and I wasn't too concerned about it, but it's taking a little longer than I would like. Does anyone know what this is or if it has anything to do with achilles tendonitis? Thanks.
