Today I did a cut on my arm. It's strange though because it's LESS than 1 MILLIMETRE deep yet there is a yellow and bubbly bit sticking out of the wound which I believe to be fat.

It's too late to get stitches and to be honest, the wound isnt deep enough. What can I do ?

Leave it out for it to dry out or keep it covered with the dressing and bandage I am using now ?

So...

1. Should I leave it covered or open
2. How long should I keep it covered before being able to let air get to it
3. How can I reduce the pain it is causing me
4. What should I cover the wound with ?
5. How come I got down to the fat layer with such an undeep cut ?

Please help me. I regret all of the cuts on my at the moment. I just want this wound to heal ASAP so I can get on with everything.

NEVER going to cut again!
