Basketball players do it all the time. It is perfectly fine to do so.
However, if the finger is your fore-finger, it may be tough. Shooting, passing, and most other actions other than just defending involve the fore-finger.
If you have a jammed finger and the tendon is torn away from its attachment, you will not be able to bend it at all. You will have pain on both sides of the finger and joints.
Traffic was jammed in both directions.I jammed my toe.She jammed her finger when she fell.
put ice on it and go to a doctor
Go to the Emergency Room to have it re-set.
Ice; possibly Ibuprofen, if it's not bleeding.
I really don't know ask a doctor or something.
This means either your finger is broken or jammed. If you can move it, it could possibly be slightly cracked. And it can be severely jammed. If your finger, though, you should tell an adult or tell a doctor ASAP.
with your finger
This depends on how badly you have jammed it. Usually if you can still get movement out of you finger you caan immediately return to your sport but you may want to tape it or get a splint. If you can't get any movement out of your finger I suggest going and getting X-rays because it may be fractured or even broken. Hope this helps! :)
I used to play basketball and have jammed each of my fingers several times. Usually my coach would pull the finger out if it had not repaired itself. Then I would tape the finger (individually for my thumb) and then apply ice. My mom looked it up online and I still have the link which provides a more "medical" approach to it though... http://www.sportsinjurybulletin.com/archive/finger-injuries.html
The best description of the feeling is like....When you "Jam" a finger....like getting basketball off the tip of a finger wrong....suddenly feels swollen but my not be..., hot, tingly, hypersensitive and numb at the same time. Now, my whole hands feel this way...not just a finger. And at times the intensity of this jammed finger feeling is 2 or 3 times that of just a jammed finger. Best "picture" I can paint here.
Yes, it is very normal for a jammed finger to swell.
