My lower right leg has been really sore for a few days now. It hurts between the ankle and my lower calf, a sharp pain. Hurts mostly while running (especially the first few hundred meters of a run) and climbing up and down stairs (and stuff like that). Sometimes it also feels tight (sort of like a pinching) in my achilles.
Any ideas on what could be wrong? How to treat it, am I making it worse by continuing to run on it?
Thanks.
