Still Having Pain 5 Weeks Post Op, Possible Causes?

Thanks for your question.  You are still at a very early phase of the healing process.  The pain you are experiencing is from sensory nerves that can take months to finally "calm down" after elective facial surgery.  massage might help in certain situation.  Otherwise the best solution is time.  I know that isn't a very satisfying solution but given enough time your pain will abate and the nerves will be significantly less irritated and swollen.

With the hematomas and swelling and bruising, you inflammatory stage will be more pronounced and with more pain. This will get better with time. Treatment would include usage of different types of pain medication including benzodiazepines, opiates, muscle relaxants, tricyclic anti depressants, etc. I would start these slowly and only followed by someone who is experienced in doing this. Steroid injections will help in the areas that are really painful as well.
