What is this 😫😫

Wtf is this big lump on top of my daith piercing? I got it done like 22/12/17 so its not that old but I try to keep it clean. I am guilty of fiddling and turning the ring round, is this just a result of doing that without washing my hands? What would you guys recommend for getting rid of it as its hard and painful to the touch. Anyone else had loads of problems with their daith? Thanks!
