Do you know what's on my arm?

It looks green. When I squeeze it, dark greenish brown stuff comes out. It looks as if it's within a pore because I have to force the stuff out, it doesn't purely start to come out by itself. When I take some out it have a wierd smell to it. Can anyone seriously help? Please no stupid answersDo you know what's on my arm?
Sounds approaching you have get some sort of infection. Do you know if you got bit by something? Is in that redness around it or a string from it that is red and is it hot to the touch? If so draw from to the doctors. Those are signs of bad infections. It sounds close to it may be a spider bite. If you squeeze it again and it has an widen spot on it put hydrogen peroxide on it, that will bubble out some of the infection, then put resembling neosporin on it and leave it alone. If it does not show expansion or gets any better I would shift to the doctor. You may need an antibiotic to rid the infection from the inside out. Good luck.
I dunno...gangrene?
I believe you should have a doctor look at that.
Did you get hold of a bite?
Go to a doctor. It doesn't sound dutiful.
sound resembling you either have gotten bitten by an insect or had a small cut . try wash it out and applying triple antibotic, it should clear up in a few days, except go see a doctor.
progress see a dermatologist
