Should I be concerned ? 31 + 2

Today I was out eating with the family and then out of nowhere, i started having really bad lower backaches and feeling queasy and as if I had to throw up .. and within 5 minutes my body was dripping in sweat like my face literally was soaked and my heart was racing. I ended up heading to the car as I felt so weird as if I’d faint . I didn’t end up fainting or anything and the restaurant wasn’t even hot inside .. I’m home now laying down .
