Hello. I Have Swelling And A Achy Stinging Pain In
Hello. I have swelling and a achy stinging pain in the back of my knee. There is also a blueish area on it. I've not hurt it or fallen or anything. I have swelling and pain in the front of this knee from time to time but haven't ever had this in the back of it.
