I have a rash on top of my arm. It is red and slightly blochy. It hurts really bad especially when I shower.

Hi, have you or any of your family got exzma? It's a skin condition which becomes quite weepy and very itchy and red. Its very common, even I have it, you usually get it in cracks, e.g. armitts, ears, fingers arms, you can get it easily treated. You can go to the doctor and they would give you proper cream which gets rid very easy, or you can go to the supermarket and by e45, which also very good help.

Oh no! Maybe is it a bug bite? I had a spider bite on my arm and it was like that. Try putting antispetic cream on it. I suggest Tea tree antispetic cream from Thursday plantation *if your from aus* Then put a bandaid on top? (: Go see a dacotor
