I'm screwed...

One of my pedals is stuck and I have no clue what to do now. I've been using the park pedal wrench but the pedal is stuck on and I've stripped all but one side of the pedal and the hex side isn't working either. I've tried wacking on the pedal and of course its not helping. Should I take a small soldering torch to the crank? Any ideas? take it to the LBS?
