Skin creases on finger(lower side&back)seem stretched/more evident, after 1month coban wrap(pip joint), while normal movement&stretching.what can i do?

Why was it wrapped?: Depending on why it was wrapped will determine how to proceed. If for a cut or sprain then it will resolve over about 96hrs. If there is any chance of an omfectio(redness, fever, streaking along the side of the finger ) then seek medical at tension.

The pip joint: Creases on top of the finger can go "missing" for a time if the joint is swollen and stiff. The skin there is very flexible and if the jointis bent a little or the joint is full the creases look different. The creases dont really strethc they just look different until time passesif and when / after the mechanics normalize.
