HELP!i dont know whats wrong with my finger?

Okay,so a week back i hurt my finger,and to keep the injury in place i put wrap around it,and a thumb splint.

i just took the wrap off.
and my finger was very white,and extremely wrinkley,and itchy,
and when i itch it, it hurts and the skin comes off.
please help! :( i dont know whats wrong,and i dont want to have to cut off my thumb or somethingg!

Your bandage got wet and the skin is reacting to it. Keep the bandage off, allow it to get air and dry out, Do not scratch it. Don't put any salve or ointment on it for now because this will only impede the drying process

it is white because it got wet and had no air..and wrinkly because it was wet for days. keep bandage off and it will get better don't worry

you probably had the bandage on too tight and didnt take it off often enough for the skin to get some air. the skin is white because its dead/wet skin. its alright just dont bandage so tightly next time.

Phone nhs direct thye will give you good advice, hope it gets better soon.

normal stuff

I agree with all the answers below . although i dont know exactly how you hurt your finger and what exactly happened etc. but the white and wrinkly skin is perfectly explanatory.
ever noticed swimming for a long time how your fingers will look real white and days after days of it they will be wrinkly on the tips well pretty much same thing. wrapped it to tight or even if not you need to peridoically remove the bandage to clean the area let the wounder area dry. air out. re appkly any type dressing/ointments and re bandage. in this case i dont think you need any ointments and try leaving the bandage off but to be on the 100% safe side i would recomend having a doctor or nurse look at it. but the itching, skin peeling, wrinkly
very white it from mositure and no air to dry. its dead skin now its exposed to air it will start to itch. the skin will peel off and new layer of skin will grow. just ensure you can move the finger freely . bend it grasp etc... if so then just clean it well. and let it get air.

Its just from the skin not getting enough air and circulation to it. Dont put the wrap back on it for a while and if you do take it off like every 2 hrs to give your skin time to breathe.

It very much sounds like you have the early symptoms of Leprosy.

I would go to your local dr or er. because when you put it in the splint you might have shifted the injury. and more might have to be done.
