I received juvederm ultra filler in my hollow temples two weeks ago and now my right cheek is swollen.

Swelling after fillers is very common (even in areas close to the injection site) and sometimes can last up to 5 - 6 weeks. If you are still have problems a month and a half after your treatment, contact your provider. 

Please follow up with your treating physician for an examination and discussion of potential causes for the issue.

I would return to your injector for an evaluation.  It is not contraindicated to fly after having a Juvederm treatment.  It is best to speak with your provider to assess the symptoms you are experiencing.

I don't restrict my patients on flying and the swelling is not related to that. I'm not sure what the swelling is but I would discuss with your provider. It could be completely unrelated to the injection. I'm also not sure of the degree of the problem. You shouldn't have swelling after 2 weeks from filler in this area.

I would immediately return to your board certified treating dermatologist for evaluation.  It may be sign of infection or other problem since there should not be swelling in an  area that was not directly injected.  Please keep us posted.  Best, Dr. Green

I concur please return to your injector. 
If there is pain or increasing swelling you would be wise to seek urgent medical attention.

Please return to your doctor for assessment to see if the swelling is related to your Juvederm injections.
