Yes, 0.4 percent of patients who are given Prolia may suffer from cellulitis or erysipelas.
There is a chance that you might get cellulitis again from the injection as well. If the Prolia worked for you as far as your osteoporosis is concerned then the risk of cellulitis is out weighed by its benefits and you can actually opt to get the injection again, keeping cellulitis as a possible side effect in mind. But if the prolia did not have any benefit, then I would suggest that you ask your doctor to put you on Alendronate or Alendronic acid, 10 mg daily or 70 mg weekly. It is also a bisphosphonate and has good results in both treatment and prophylaxis of osteoporosis in women.
I also suggest that you visit a nutritionist to chalk out a diet plan in which calcium is in abundance. Your doctor should also have you on vitamin D supplement and calcium supplement.
