I had a nail in tire, in about the same place last month, took it Discount Tire. Got the whole "What if" speech about if it's not repairable. It was just fine repaired and patched. @sidewinder picture of the repairable zone is a really good graphic, if your within it. Plug it and you'll be good. If you're feeling uneasy plug it, inflate the tire, then take it to your local tire shop and have them look at it.
