Hi. A few weeks ago I bent my middle finger back while carrying something. I felt a pop and experienced pain when trying to grasp something. I iced the knuckle on the back of my hand then taped my middle finger to my ring finger on and off for about two weeks. I though I was almost all healed. My finger is straight and I can make a fist without pain, but now the knuckle at the juncture of my finger and hand is turning black & blue and is sensitive to touch. Is there anything I should be doing now?
