wrap your hand wraps tight and this maybe causing your problems

i started hitting the bag again recently after more than a decade out and my hands at first were in bits ,cuts bruises and painful . i went on holiday for a couple of weeks and when i started again they didn't hurt anymore , i think i needed to rest them for a while as my fists wasn't used to being used.

I use the wraps, not wrap gloves, and my knuckles still get skinned a bit whenever I wrap my hands by myself. If a trainer helps me, they don't get skinned... Am I wrapping too loose, too tight, or what? What am I doing wrong?
