If it was done with a gun, that's pretty normal. If it was, and they gave you some solution stuff, don't use it. Stick to sea-salt soaks instead (1/4tsp sea salt to 8oz hot/warm water). Much better.
Also, if it was done with a gun you may be sensitive to the crap jewellery and you might wanna get the jewellery changed to a titanium barbell.
But yeah, whether needle or gun, stick to sea salt soaks and make sure you keep hair products away from it, change your pillowcase and stuff too. And try not to use that ear for your phone.
