Hematoma After Radiesse Injection?

Bruising and swelling on the left side will resolve with time. If you truly have a hematoma (blood clot) on the left side, that can take up to a month or even longer to resolve fully. Localized application of heat and gentle massage of the left lower eyelid area would encourage the bruising to resolve faster.
Arnica Montana (available at health food stores in pill and gel form) can be helpful. Beware of the uncommon allergic reaction to this herbal product. I would suggest waiting 1 month before anything further is done at which time any irregularities or asymmetries can be addressed.

Bruising and swelling can occur from any injection. In reviewing your photograph I only see what appears to be some skin bruising but not any gross swelling.  That should go away in a few days.  Initially bruising and swelling may be perceived as uneven results but that will settle down in a few days.

JSR:  From your photo, it looks like you got an unfortunate but common side effect after fillers around the eyes-- bruising and swelling.  Without examining you, it's difficult to say if you may have a small hematoma (a blood collection under the skin)-- but looking at the photo, it looks like it is mostly bruising on the surface of the skin.

Because the eyelid areas have lots of blood vessel and is thin, it is very prone to bruising.  I warn all my patients that I may bruise them if we treat this area.  Fortunately, if my patients get a bruise, I can use a pulsed dye laser 1-2 days after treatment to help these bruises go away.  

As for the results of the injection, I would give it a few weeks after the initial swelling and bruising have resolved to judge.  All fillers can initially cause some swelling that can be seen as uneven results the first few week.  Give it more time to settle.  

Best,
