I have a hard red bump with white on top of it on my ankle, it was smaller months before and it doesn t hurt, but it is growing Ikknow because it s bigger than before, but still only very small. What could it be? I can scratch the deadwhite sskin off the top but the bump is still there, it s NOT a zit and it s HARD. I also lung nodules but don t know if that has anything to do with it, my lung Doctor says he thinks my lung nodules are ok though, Ihave aanother CT Scan in February if they haven t grown then he says Iddon t need anymore CT scans again because Ihhave had 3 scans already...
