Bump On Lip Piercing White Bump Underneath Lip Piercing?

White bump underneath lip piercing? - bump on lip piercing

My lips pierced about 6 months. It was the last week of August and had no problem with him. I cleaned and all that good stuff and seems to heal completely right! I did not cause swelling or irritation. Nothing special. So I guess about 4-5 days, I realized that I had a lump under the lip piercing. I have a standard and have for a while. It does not hurt or what .. But it is there. It is in the mouth under the right rear of the stud that goes through the bar. I'm just curious if anyone knows what it is, or knows how to get rid of him. I do the normal cleaning of new and all .. but if someone knows something, what can I do, please let me know!
