hi, i found one small lump on my leg under the skin, i ran the day before so my leg was sore that's when i notice a small but very hard lump that you can defianly tell its a lump (between the knee and the foot). I just don't know if its very serious or just something simple because i have never heard of someone having cancer or a tumor or anything like that serious with their leg.
So just wanted to ask someone as to what is it and what should i do should i be worried?
