Swelling/Redness Every 10 Days from Evolence in Lower Orbital, Near Nose. Normal?

To fill a dent, I had Evolence injections on the lower orbital of the right eye, near the nose, 3 years ago (2009). My surgeon recommended the new product, Evolence, stating it was the "softest filler on the market" and would last 6-9 months. The lump remains and, 9 months ago, it began to swell and turn red every month. Now, redness and swelling occurs on a shorter cycle, every 10 days, and lasts 4 days. Swelling/R edness, feels tight, and stings. Worst upon first awakening in AM. What to do?
