Lump appeared after skin biopsy concern. (Photo)

Hi! 1 month are go I went to a skin doctor for a routine check and concern about a few moles, the moles were removed and sent for biopsy and were returned all benign. the 3 mole removed started to heal, 2 on my arm and 1 on my face, the face and 1 on the arm healed normally. But 1 spot on the arm gotten hard and lump-like, a little itchy as well. It smooth and a little raised. I cannot visit the doctor right now (out of country) but I wonder if this is normal and if it will go away.
