Today i found a bump on my outer thigh. Its swollen, and red, but i dont know what caused it. Could it be a spider bite? It dosn't itch, and it dosnt have any puss or a white tip. It has the shape of a mosquito bite sized pimple, but without the white tip and without the itchiness. It hurts with the slightest touch, and it hurts without a touch. Its like i can feel it pulsing just sitting down. Can you please give me some advice as to what it may be?
