My primary advice is that you go back to see your primary care doctor
, or whichever doctor initially diagnosed and treated the fracture
, for followup.
When you fracture a bone in the finger, this can often take quite a while to heal, mostly because the fingers are used constantly, so it is hard to keep the finger still enough for long enough to encourage healing. One possibility is that the splint may have been removed too early and that now things are not continuing to heal up as desired. Your doctor can examine the finger for any signs of this, and they may decide that you need another X-ray
to take a look at how things are progressing.
Sometimes, with particularly poorly healing finger fractures, it may be necessary to get specialist help from an orthopedic doctor. Your primary care doctor can help determine whether or not this is necessary in for case and, if so, they can make the necessary referral for you.
In the meantime, your primary care doctor will also be able to give you some advice about which medications you should be taking right now to help with the pain and the swelling.
