Stretched ears are sore and crusty?

I started stretching my ears two days ago and used acrylic tapers. I then put acrylic plugs in after stretching them. I know acrylic isn't good, but that's all I had and I'm buying stainless steel plugs this weekend. But, I woke up this morning and my ears were slightly sore and had a bit of crust on the back of them. I've been cleaning them twice a day in the shower with warm water and sea salt.
