3 months post op. Why is the skin under my nose tight? Can a columella be widened/protruding if it was thinned/retracted?

My nose was overlyshortened and i no longer have columella nor infratip. The little piece of columella i have is thin and retracted. Why when i try to rub my lips it doesnt stretch all the way down and feels tight? Could it be that skin was cut off? Also if i lift my eyebrows to wrinkle my forehead, i feel the skin on the nose stretch
