I woke up yesterday with swollen eyes and cheekbones. I have hives on my back and neck and a few bumps on fron neck, forehead and a red spots on my cheeks. At first I thought the swelling on my eyes was allergic reaction to benadryl. But for a while after icing my eyes, the swelling went away not completely, tho the cheekbone swelling went away slightly. I then took again another benadryl in morning and 1 in afternoon. I applied hydrocortisone ointment on my back and neck twice yesterday and once just now including on the swollen eyes and cheekbones. I kept icing my cheekbones but does not subside completely. The red spot on my cheek left is gone. I did not take benadryl before I slept to eliminate possible cause of my swelling. At 2:20 a.m. today I woke up my eyes and cheekbones swollen. I started am icing it now I woke up and my eyes and after I applied the hydrocotrisone ointment and looks like the eyes are getting better only cheekbones swelling aocheekbones are swollen again unchanged. What could this be.
