I tripped on a pillow in the floor in a bedroom and hit my left arm (on the outside of the arm just below the elbow) on the dresser as I fell. I had immediate bruising. It was a huge bruise. I applied ice and the bruising went away within a week or so. However, it has been about a month ago and I still have a 2 in x 2 in swollen area that is firm in that area. Is this something I need to see my doctor with or will it heal?
Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have bruise on left arm after having an injury. Well there can be many reasons for symptoms you mention in query like hematoma, soft tissue injury or infection. I would suggest you to apply ice pack thrice a day, take ibuprofen or acetaminophen and keep your arm elevated while lying down. If condition doesn't get well then consult general practitioner for proper examination. Doctor will examine physically and prescribe anticoagulant like heparin or main Chat Doctor.  Doctor may also prescribe antibiotics along with anti-inflammatory. Hope your concern has been resolved. Get Well Soon. Best Wishes,
