So I have a huge swollen bruise at the bottom of my left calf after weightlifting yesterday, I think from hamstring curls.  I'm worried now that either I'm lifting too much with one leg or setting the machine wrong.  I have soreness and pain through that leg too so I'm hoping I didn't do more than bruise it.  Although I got through my run Ok today.  Any suggestions on fixing my form or the settings on the machine?  **  I think I'll do deadlifts when I do legs this week instead of curls to avoid the machine altogether until it heals.  Thanks!
