Hi, my 10 year old son is in terrible pain all of a sudden due to a hard lump with purple bruising on the back of his leg(the back of his knee where the crease of the leg is). It just happened all of a sudden, it was not there this morning and he didn t fall or get a knock at school. I am worried, should I take him to the doctor or hospital even? Thanks.
