Is it normal for Your whole ear to be extremely sore after an Industrial / Scaffolding piercing ?
Yup that sounds about right. You have to understand, you just had two cartilage piercings done; as piercings go, cartilage is about the most traumatic thing you can pierce on your body (except for very exotic and extremely rare piercings). You also have to understand, that inserting the single barbell into two fresh cartilage piercings is pretty traumatic too. So an industrial is like a double wammy for your ear. My industrial made half my head sore for a couple of days lol. So I'd say you're probably fine. Don't worry.
I had my industrial for 13 months and it never healed. I decided to retire it and the piercing sites closed up within 6 hours. Seriously, my advice to you is to just take it out. They are wayyyy more trouble than they are worth.
If it's top to bottom, then yes. If it's on an angle, then yes, just keep cleaning it.
