For the past month, I have had a painful lump on the outer side of my right knee that keeps getting bigger. I want to say it's on the joint line, but I'm not entirely sure. The skin below it is extremely itchy and feels like it's burning, and two of my toes feel numb. Standing all day at work probably doesn't help any, but should I go to the doctor or what?
Lumps located in and around the knee are usually benign.
When this lump is located along the joint line on lateral aspect of knee, the lump is indicative for meniscal cyst, due to meniscal tear (menisci are pads of cartilaginous tissue which serve to disperse friction in the knee joint between the lower leg (tibia) and the thigh (femur)).
This can result from certain trauma in knee area.
