question on bike
 

havent been around here in awhile guys. But yesterday while I was riding my crankset stopped rotating. It looked like it was moving all crooked while I was riding then it just stopped rotating. Recently me and my buddy had a 3 hour ride mud riding and our bikes were caked in mud, I have a feeling this has something to do with my bike not working. The front derailler isn't working properly and the brakes aren't either. My question is what you guys think I should do about this? Do you think my crankset needs to be replaced? Should I bring it to a bike shop to be looked at?

Sounds like the BB to me
Could be
Possibly, but it may not NEED to be
Chances are based on the post; yeah you need to take it in.
