good day , Two weeks ago i found out a lump in the size of pea in the lower part of my leg in the area between my knee and foot on the side part , it is colorless and painless unless i push it , then it started to pain a little bit , it has an extension just a few centimeters , i was wondering what kind of lump ? iam not a person who does sport but iam not a fat person , a thin man , and recently i did a few jogging just for a few minutes , then i started to feel some pains in the bones of my legs between my knee and foot due to sudden running that my body was not used on and a while later i discovered this lump so what could this be ??? can it be a cancer but the area is not a common place for cancer i would be very appreciative to you sir if you could help me ? thank you
