Hole in oil pan

Hello All;;;

I recently put a hole in my oil pan. After I hit it, I drove a few hundred feet before the light/buzzer went crazy, and then a few more hundred feet to a parking spot. I got it towed and there was a generous amount of oil under the car, so i had high hopes for the engine.

I patched the hole, but the engine does not sound good. No oil pressure i think. Oil light still blinks.

Any ideas...is this worth bringing to someone to check out....it seems as though anything internal is going to be big bucks. Any advice would be great.

Thanks
