It sounds like you really smashed your finger. I am worried that since your finger is still swollen and painful 2 months after the injury
, that you may have injured a ligament or maybe even had a small fracture. These types of jam injures such as when you are catching a football tend to be quite painful, but are fully healed within a couple weeks. The fact that you are still having pain means that there is still active inflammation in you finger. This inflammation means that either there is still injured tissue, or that your injury was more severe than you initially thought. When you are young, these types of injuries shouldn't be ignored because they can occasionally result in chronic problems with your fingers.
Because you have not had a full recovery after 2 months, I suggest that you schedule an appointment with an orthopedic hand specialist. He or she can examine your finger and take x-rays to see if there are any heeling fractures. I don't think that you will need any surgery
, but it is possible. Either way, you will be able to determine for sure what is wrong and get the right treatment. Your doctor
may recommend anti-inflammatory medications to reduce the inflammation and pain in your finger. Good luck.
