@turquoise-- You need to see your doctor. I'm not a doctor so all I can tell you is my opinion.
The symptoms of a broken and a jammed finger may be similar, but the broken finger will be more serious. You will have a lot of pain and swelling if it's broken. You won't be able to move your finger. With a jammed finger, it will still hurt a little bit but you can move your finger and it won't be as swollen as a broken finger.
But if it's not getting better, and if you still have finger pain, you need to see your doctor. They will take an x-ray and tell you what you need to do.
