Does anybody else have a lump near the elbow crease?

I noticed my right arm has a lump that hurts when I touch it, my whole arm hurts sometimes too and I barely use it. Do you know what this could be? Is it normal? Should I go to the doctor?

this isn't my arm in just showing the lump would be on the top of the arm on the left
