I was cleaning house in July 2017, and I injured the middle finger in my right hand, I was pushing a sponge into the crease of a sofa to clean out the dust balls. while pushing down, I hit the wood in the joint of the sofa. my finger is now swollen, slight bruising/ discoloration under the skin, i am now moving my finger and it is soar every day. when i put it in a splint, it feels good but I work daily and I have to type everyday so I cannot put it in a splint all day long. As for the finger, could I have injured the cartelidge between the finger bones? because the finger is moving fine, just really soar and still swollen for the last four months.. Aida
