I can bend the fingertip at the joint now, but let me tell you, this scar tissue thing is bizarre. Moving normally means feeling like a rubber band is wrapped several times too tightly around my fingertip. I'm now alternating out vitamin E oil and Neosporin under the bandages. Still can't type with it, but I think I've sped up the WPMs, and it is getting slowly less prone to pain.
The fingertip is still very numb and trying to train myself to type with it again is proving difficult for 2 reasons: 1, I 've adapted to typing without it. I only occasionally am slowed down by the need for successive use of T and R. 2, typing with a numb finger is weird. It's like walking on stilts or something. It doesn't hurt, but, I have no sense of if I have or have not hit the right key; I can't feel the gaps between keys or where the fingertip is located on the key itself. Weird, weird, weird. Also strange is using a touch screen.
The skin is completely sealed now, but is patchy and pink as the new skin breaks in. The scar tissue is lumpy, uneven, and some bits are incredibly sensitive. Not painful, just super-sensing, as if the nerve ends all relocated to one spot. My massage therapist gave me some advice.
She said to work on the sensitive spots more than the numb ones. To get them used to touch and sensing, reorient them to to the necessary level of sensitivity by gentle massage, an occasional hot-salt-water soak. It's almost like the nerves need to be comforted, reassured that the danger is past, that injury is not always imminent.
Exercising the tendons and muscles, too, is necessary. They all need to be reminded again that normal function is possible, that small successes are ok, and, over time, will lead to healing.
