Lump from cannula in hand

Just Me • Have a 4 year old daughter and a Newborn GLOW baby girl born 22/04/15..so in love 💕
So I Was induced 6 weeks ago with my daughter for medicinal reasons. I had to have a cannula in each hand one for the induction medicine and one for fluids and a insulin scale drip. Well the place they where inserted has healed and scared but I have a non painful lump in hand still from it. It's moveable also. Any idea?
