Not necessarily. I've tore my left quad and left soleus. Diagnosed by a physician. Lots of swelling in the quad. No bruising. No bruising or swelling in the soleus. Just lots of pain. Prolly depends on severity.
if you got insurance go have it checked out if you don't i understand as i have a strained or minor tear in a bicep tendon that i cant have checked out cause of no insurance.... i'm changing up workouts and going to give it some rest....
