i sustained an impact on my forehead 3 weeks ago, playing football an opponent landed on top of me connecting via the elbow. the soft swelling went down within days but a surprisingly hard lump has remained, marble sized, and has in no way dissapated. it is somewhat noticeable and i am curious as to whether this is normal?
HI. This is not normal. This marble sized lump can be a collection under the periosteum of the skull bone hence not resolved. Consult a Doctor. After 3 weeks this must have been organized, aspiration may not yield any blood. You can take anti-inflammatory tablet and give it time to heal on its own.
