I have a lump on my shin that has been there for a couple weeks. I bruised it playing soccer - it swelled up slightly and I had a huge bruise right away. The bruise is now gone, but I still have a lump/knot on the injury site that is only painful when I touch it. Is this an issue, or will it heal on its own?
It could be an infected sebaceous cyst or just hair infection or an abscess course of antibiotics is recommended in worse case you need to consult a surgeon all the best!
