helix piercing

so i got my right helix pierced (ear). i tend to sleep on my left, but i will sleep on both sides. i haven’t been able to sleep on my right, obviously, because my piercing hurts, but because of this, my neck has been fucking KILLING me. i’ve been getting insane headaches because of it. has anyone went through this when they’ve gotten their ear pierced? and realistically, how long until i can sleep on the pierced side?
