Can too much salt make you sick?

I had a curry and it was very salty within seconds of eating it i felt like pins and needles in my chest.I didn't finish all the curry but ate most of it, about 5 Min's later i went dizzy and i was sweating all night i don't have high blood pressure it has always been low .I was just wondering if i had a salt overdose.i have asked this question before but we all still talk about this at work as i wasn't the only person ill that night.
