for a couple of years i have had like a tightening in my chest as i try to go to sleep - then i started waking up and i wasnt breathing, i could taste what i thought was sick at the back of my throat and i am gasping for breath, it feels like my throat has closed but after a few gasps i start breathing again - now twice i have woken up with pains across my chest and back and when i sit up i feel as if i am going to pass out i feel very hot and am sweating and my legs are wobbley, the second time it happened i felt sick as well - i am however able to breath normally - i am very scared to go to sleep - i had an ecg which showed my heart was ok so what can this be - i was given tablets to stop my stomach making acid but its happened again - my husband has said i now snore alot maybe this has something to do with it ? i am a young 42 yr old female - could it be 'the change'
