My dog has fluid-filled lumps but acts normal. Is it a hematoma? Vet?

My dog has developed these fluid-filled, soft sacs over the last 24 hours. She is acting completely normal and playful, but I gave her a benadryl in case it was an allergic reaction. I think the one under her arm is a hematoma. Does she need to see a vet?

Poor Layla! It could be that she is having an allergic reaction, and oftentimes that requires stronger drugs than OTC ones to treat. Yes, I would have her seen by a vet for this problem. Best of luck.
