Solutions for pedals screwed in the wrong sides? I have a Focale44 fixie with a single speed on the other side of the gear (this is called a flip-flop I think?) and I LOVE it so far! I've ridden it for about six months and haven't had to fix anything big on it yet.

The only problem is that I must have screwed the pedals in the wrong sides and now I can't get them back out. But, in trying to fix this, I'm really hoping not to have to buy a whole new crankset.

Any recommendations on this one? Here is the crankset...Focale 44 Crankset

Can I still ride it? I can't really afford to replace anything for a few weeks and I might die if I don't get to ride during that time! Can I just replace the arms? If not, what cranks can you recommend? I really can't drop any more than about $100 on this.
I doubt that you actually managed to screw your pedals into the wrong sides.  If it can even be done, the amount of force required to do so would have easily alerted you that you were doing something dreadfully wrong.  Not to mention the aluminum shavings that would have been all over the place.

Pedals can get pretty snug just through the action of peddling the bike and it may take quite a bit of force to get the unscrewing action started.

Also remember that crank arms and pedals are threaded so that the action of pedalling the bike does not cause the pedal to loosen and fall off.  This means that on one side of the bike, the right/chain side, the pedal is threaded as a regular clockwise to tighten, counter clockwise to loosen bolt.  The left-hand crank is threaded in the opposite direction.

Don't be afraid to apply a good amount of force (in the right direction) to loosen the pedals.  If they are threaded correctly, it would be quite difficult to ruin them by applying too much force.  If they actually are threaded incorrectly, the crank arms are ruined anyway, so you're not going to make things worse.
