Hello :) well i noticed yesterday that i had a pink lump on the back of my heel and today when i was walking, and my shoe kept rubbing against it, it hurt a lot. Then when i checked it when i got home the skin on it had peeled off and there was like a clearn liquid oozing out of it... can you please tell me what this is and how i can make it better? i have to be able to walk comfortably because i start school tomorrow.
