question: My 8 month-old daughter has a swollen and red right forearm. We noticed it about 1 and a half weeks ago but thought she may have strained a muscle doing row-row the boat with an over-enthusiastic 3 year-old. It seemed to improve but today it looks worse again. Apart from that, she is fine in herself, the arm doesn t seem painful to touch and she is putting weight on it when she crawls, etc. What could this be? Thank you.
