I'm a 30 year old female. 3.5 months ago, I slipped in the bathroom, hit my forehead on the hard tile wall. Within hours I had a large bump above my eye on my forehead. Swelling went down after 2 weeks, but now 3.5 months later, there is still a small hard bump under the skin. Not painful, but slight discomfort if I touch it and sometimes I will get a small tension headache if I put pressure on the bump. Should I be concerned? Should I see a doctor? Thank you.
