How were they pierced? Gold is not pure enough to wear in a healing piercing, you need to be finding titanium or high grade surgical steel until you've completely healed it. 24 karat gold is too soft and contains impurities in the bumps, but 14k and 18k are both mixed with other metals which you could be reacting to. If you were pierced with a gun, the pressure build up from not having any flesh removed can make healing much more complex. If it's been completed with a needle then take it back to where you had it done and ask them to change your jewellery and take a look at what is causing the upset.
After that, it is always best to leave the piercing completely alone. Completely alone. The LITHA (leave it the hell alone) method is the preferred as it doesn't introduce bacteria through cleaning or disrupt the piercings through turning it around and disrupting the little fleshy tube you want your ear to make.
Check your diet is sufficient to heal a piercing - it's only a tiny hole but something is disrupting healing, it could be an external issues, or it could be that your body is struggling to heal.
