I got my nose pierced in May, and I changed it to a ring a few days ago. Today I discovered that it is extremely sore and tender to touch, almost as though somebody has hit me in the piercing. It is swollen and red and looks really sore. Does anybody have any idea what this is and how I can solve it? Thanks

Is there puss coming out?
What kind of metal did you change it to? You might be allergic to it.
Is the gauge a bit larger than the previous ring? Your piercing might be too small.
Change you ring to a non-metal(plastic inserts -forgot what they're called). Of go back to your old nose ring. Sterilize rings before you put them on. If you're picking your nose use a q-tip. I suggest that you go to the doctor just to it checked out since your nose is really close to the eyes, mouth and brain. You just never know :)
