Hamstring Worry.?!

Hamstring Worry.?

Ok, so I pulled my hamstring badly, no doubt about that. Basically I was just coming back from a pulled hamstring injury on saturday, and strained it at the very start of the rugby match, and decided i'd play through the pain. Stupid i know.

Now I have a MASSIVE bruise down the back of my leg. I'm worried that I have more than merely pulled it though...

How do you know if you have RUPTURED the muscle? As in, rupture involving surgery?

Thanks.

Both of these websites have excellent information on symptoms and treatments for hamstring tears, strains, or ruptures.
Best of luck, I am still having trouble with mine that I pulled during fall tennis season.
