Dark Spot Under Eye After Injections? (photo)

In 07 I had lower bleph & was left looking hollow. In 2010 doctor put 1cc Radiesse near my cheekbone. 4mth later another 1cc under my eye & I was SEVERLY bruised under 1 eye for WEEKS (2cc total!). 2011 I got .2 juviderm under my eyes. Its been 15mth since I have done anything to my eyes. I have a dark spot under 1 eye that looks esp terrible in florescent light & Im puffy on that eye. Is the spot from tyndall or veins or...What do you suggest for the spot & darkness in general under eyes?
