Kaz, 25 yrs experience (you didnt get it done in Bath place did you)... Seriously I told you before a lump by year piercing need a few days treating with hydrogen peroxide. Apply it with an ear bud, if this doesnt work, go for hot compresses for a few days, if this still doesnt work and you still have a granuloma. Take the stud out for a few days till the lump goes down, should be a few days, anything up to 5 then reinsert. If it flares up again take the stud out all together, then have it repierced a few weeks later.
Im pretty experienced when it comes to piercings. I have had many over the years and my nose piercing is 17 years old now. Stop touching it, rotate it when you wash your face twice a day, the wound should be wet when you do it.
