My needle won't move nor will the wheel! How can I fix it?

I was in mid project and it jammed. I got the bobbin and casing of that out. I can't undo the needle, it is on there too tight! The wheel won't move but a smidge in either direction. I took the outside casing off and found that the rod that comes up from the needle inside is barely moving...Maybe that is it?!?! Anyway, how do I fix this or is it a lost cause?
