Hi thanks for your qestion.
The lump between your scrotum
and thigh most probably could be a small lymph
node ( normally present there),a lipoma
(a benign fatty tumor
) or a small boil.The pimple in the ear most proably could be a boil.All these conditions are benign and there is nothing to worry.I would suggest you to consult a physician who will examine you both lump.
Hope this answers your question.
