Eyebrow piercing bump

My piercing is 4 months old and about a week ago I noticed a hard lump underneath/around it. I honestly haven’t been consistent with the upkeep of my piercing so I fear that may be why. I’m unsure of what to do or how to get rid of the lump. Do I go to my piercer or is this something more serious that I have to see a doctor for? It doesn’t really hurt unless I touch my piercing, but I’m still worried.
