Welcome to HCM. I m sorry for your situation. If I understood it well, you injured your finger more than two months ago. Usually, this type of injury are very painful, but tend to heal fully within a couple of weeks. Since you are still experiencing pain and lack of functionality it means that there is still some damaged inflamed tissue. I suspect that the injury was more severe then you thought. In order to prevent chronic issues with your finger, I recommend to not ignore anymore this problem. First of all you should do an x-ray to rule out any possible fracture or healing in the wrong position. One other possibility is ligament injury. You could take NSAID to reduce inflammation and for pain, but this is just symptomatic relief. I recommend to schedule an appointment with a hand specialist in order to examine you more objectively. I hope my answer helped you and I wish you a fast recovery.
