I accidentally slipped and hurt my middle finger.there's no broken bone accdg to the X-ray result but it is swollen and hurting too much.My Doctor prescribed me a Nabumetone,it's almost 4 mos. now and it still swollen.i have a history of Arthritis that started on my right toe.I feel pain in my right toe but not swollen like my middle finger.What is the best advise you can give me,im so frustrated and i have limited mobility in my finger.....thanks a lot.
