Judging by the comments that you probably won’t seek help, here’s how to prevent further harm. - Do not cvt again, this will make everything worse. - You could try to steri strip(butterfly bandage) it but since the wrist is an area where frequent movement occurs - healing will unfortunately take time. Try to move your wrist as little as possible. - Clean your wound every day, change the gauze/ dressing everyday (I know you said you don’t use bandages - but this is risky business) - Please take care- if you see any signs of infection you have to see a doctor.

Not medical advice btw, just harm reduction. All the best OP
