Hello Thank You for contacting HCM. After an injury blood accumulates under the skin. With the passage of time color of blood changes along with the overlying skin which is a normal process. I would suggest you not to worry. It will take some time to heal completely. Meanwhile you should take extra care and keep her in front of your eyes. take a cloth and warm it over flame and put it over the forehead. It will give soothing effect to her Continue to give analgesics as advised by your doctor. Report to hospital if: There is loss of consciousness Blurred vision She becomes lethargic She Vomits Bleeding from wound or nose Any unusual symptom Hope this answers your question.
