I pierced my ear 2 days ago and I made sure I'd sterilised everything but now it still hurts 2 days on, it's red and swollen and it's letting out a bit of clear liquid which gets stuck to the ear-ring. I clean it every day but it isn't getting better, I was wondering how long it usually takes for the piecing to stop being red and swollen, also is this normal or should I go to the doctor? Thank you
