Ear piercing- when should the piercing stop hurting?

I had my ears done just over 6 weeks ago. One reacted, closed up and will have to re-heal. The other went fine. The only thing is, I've just changed the stud over (it was getting a bit manky and I wanted to take it out to squirt antiseptic into the hole) and it's a bit hot and it hurts if I pull on the earring or roll my earlobe in my fingers or anything like that. Is this normal? If not, what should I do?
