6 weeks post op of Juvederm, I have jaw pain and intermittent swelling of lips, marionette and nasolabial areas. Is this normal?

I recommend you schedule a follow up with your injector to discuss your concerns and evaluate treatment going forward. You may need to remove the product with a hyaluronidase injection. Pain at 6 weeks post injection is not normal. Hope his helps. 

6 weeks after injections with Juvederm, you should not have pain or swelling in the area.  In my experience, this is typically a sign of a low grade infection.  In this situation, I would dissolve the filler and start the patient on antibiotics.  Patients will respond well to this treatment without any long term complications.  I would advise an in person evaluation.  

I would advise you to see your injector for an evaluation. While I can't say for certain if you have an infection or something like that, swelling and pain should not be occurring 6 weeks out. Now, I'm NOT saying to panic, but at least be seen by a trained professional. "This answer has been solicited without seeing this patient and
