Finger pain, help

So recently I noticed some discomfort, Swilling regarding my middle fingers, which turned very quickly to pain making me unable to bend it,

Last few days i rode my motorcycle bit often. maybe because of the clutch?. i hadn't injured them in a crash or something, i gave them couple of days rest but still swelling and hurts badly. Am i the only one with this? Is there maybe a treatment or something besides just rest?

Specifically this part of the fingers hurt:

P:S - ts not on the joint just the middle part of the finger image
