Something else to think about

[jaywalker33]

Here's one for you, let me know what you guys think it is. I was filleting a striper back in July and one of the spines accidentally stuck my finger just below the nail on the backside of the finger. I immediatley washed it out and put peroxide and iodine on it. It hurt for a little while and was sore for a couple days. However now it feels like I have small knot in that finger on the bone. I am wondering if I actually have a small piece of the spine in my finger as the small cut closed up almost immediatley. This was in July and I still have the bump but it doesn't bother me.

I am not a doc but my money would be you have a small foreign body in there and your body encapsualted it. I had a similar thing in a finger where a small metal shaving was in my finger...after a while I had a bump and had a little tension when I bent my finger because it was near a knuckle. Had the doc look at it and she cut my finger open and removed it...I watched and it was like a little sac about the size of a pea and in the center was a tiny shard of metal. Healed up fine after that.

the bump "is or could be" scar tissue that grew around it
and that wouldn't happen if you just got an in and then out puncture wound.
