TMI question about tearing

So I only got about 3 or 4 stitches from tearing however I'm now 3 days PP and still in A LOT of pain and burning a little when I pee. Before I left the hospital I told my doctor I was still in a lot of pain and he made it seem like it was completely normal and no big deal. Could it be infected? I guess I should call in the morning I just don't want to seem annoying and have him tell me again that what I'm feeling is normal.
