Iv had my ears pierced for 4 years now and theyv been fine since then. But I used some earrings that had sort of rubber-y poles (theyr clear and feel rubbery or plasticy not sure what their made of) and since wearing them for a few days one of my piercings feels painful to put a stud in and feels sore to touch. Iv now throw out those earrings (from matalan) and have some solid silver ones in. Just took them out and the piercing that hurts was a bit crusty after it had bled abit when the stud went in. Should I just leave some studs in for a few days or weeks and keeping turning it like when they were first pierced? Anything I can put on it to keep it clean?
