I am a 14 year old girl. And there is this lump on the ball of my left foot aligned with my middle toe. It is about the size of a pencil eraser and is kind of painful when I walk. Not a sharp pain, just a sore ache. It seems to be covered in callous now, but before that I pricked it with a needle and poured peroxide on it. Sure enough, it fizzed up due to infection. I imagine it would do the same now, but it's hard to get to because of all the tough skin over it. The top is kind of rough, and the whole thing is very firm. Maybe this is a plantar wart? They're known to grow inwards underneath callous. Also, I have two more little... Things. One is on the same foot on the ball below my big toe. This one is a tiny little circle that is a bit dark in the middle. It kind of looks like an indent after stepping on a small stone, but it has been there for a couple days. It doesn't hurt, I just noticed it when looking at the larger one. And the last little one is on my right foot, same position as the other: below my big toe. This one just started to hurt a bit today. It's like a little hole, covered with skin. Are all of these plantar warts? Should I have a doctor remove them? I'm scheduled to go and have my doctor take a look at them next week. I would wait and see if they went away on their own, but I have marching band and the big one is really painful for roll steps. Any thoughts? Any recommendations for treatment/pain relief? Thank you!!
