Question: A few hours ago my knees were purple, then they started itching, whats wrong?
well a few hours ago i just happened to look at my knees, and it was just a huge circle of purple, i thought maybe they were just cold, so i ignored it, and then an hour later they started itching and feeling very uncomftable, so i looked, and they turned white, very pale,, and 2 hours later they still feel abit funny, like, i cant realy explain it, its not painful, just annoying

does anyone know what this is?
i do have bad circultion in my hands, but my knees were covered so im abit confused, plus for about a week my legs especially the inside top part has been quite itchy, but there no rashes or anything any ideas?
thank you

Answers:

It sounds like they where cold and needed to be warmed up, when they warm up they get itchy. But if not that then maybe a infection? Ive gotten a spider bite that did that too my arm. If it doesn't go away or comes back then I would see a doctor.



you should go to the doctor
