I am 65 years old, and fell off my bicycle a few days ago. Broke my glasses, hit my left cheek bone and obav have a black eye. I assumed it was swollen from impact, but am now wondering if I may have a heatoma under my left eye. I have been taking ibuprofen and icing, and elevating. at what point, if ever, do I get worried about it not dissipating. It doesn t seem bigger....but it is not going down in size - swelling
