Root Canal and still having pain

I had a root canal done on my 2nd to last molar on the right side. After having the root canal done, I went thru the necessary steps to have the temp. crown put on and so forth.  
Now just early this week, I started getting pain on the tooth that was unbearable to the point I had to put ice on the side of my face.  Did I maybe eat on it wrong? I don't know what is going on and my tooth is hurting.  Please help.

As you probably surmised this is not normal.   I would have the rct checked out and place the crown on temporarily until the tooth is totally asymptomatic.You did nothing to cause this problem.

could be alot of things from a fracture to an abcess (abscess) to the temp being high. the dentist needs to see you. do not allow the crown to be placed until the tooth no longer hurts.

I already have the permant crown on and they did the red paper to make the tooth was not too high and it was ok.  I just started getting this pain yesterday.

possibly a fracture or abcess (abscess)
