Why Am I Still Very Swollen and Bruised 32 Hours Post-Op?

I have no experience with the particular filler that you mentioned, but swelling can sometimes peak 2-3 days after filler injections. I would let everything settle out for at least two weeks. Make sure you let your doctor know about your concerns and go in sooner if the swelling worsens.

Swelling after Ellanse typically improves after 2-3 days. You can apply a cold compress. In severe cases, your provider can prescribe an anti-inflammatory

I use a lot of Ellanse in m y practice and from my experience ; Ellanse is normally injected deep into the tissues to support and augment the facial contours. From your picture your cheeks look a little uneven. This can happen however soon after injection, as can post procedural swelling. Although it is concerning it is likely to settle down. If you are still concerned after two weeks make an apppointment to see your treating practitioner. In my opinion Ellanse is one of the best fillers on the market as it overdelivers results. However it must be used my the right practitioner in the right patient in the right amounts in the right plane of tissue.
Im sure if you call the clinic they will be happy to review you 

From your photo, the placement of the filler seems a bit odd. Most physicians usually place Ellanse deep and in a way such that the cheeks' frontal projection is enhanced and the cheeks look slightly roundish, rather than the flat lumpy appearance in your case.
Over-dilution of Ellanse with more than 0.2cc of Lidocaine can cause excessive puffiness as well. 
Please wait out 2 weeks and then review with your physician again.
