[THIS IS NOT LAW, I CHOSE THE MEDICAL CATEGORY! how do i change it??] Hello. I really need an answer to this. I am having bad left shoulder pain, I have been having constant chest pain for weeks on and off now, to the point where I have woken up with a racing heart in the night (went to A and E as clearly I thought this could be heart attack, but all tests came back negative and I believed it was just a panic attack), I am scared to laugh or do anything strenuous as everytime I do my chest starts to hurt (in the left side), this morning I was really dizzy and I was laughing at something and my chest started making really loud, audible noises and was excruiating for about 30 seconds and then stopped. I have been prescribed Propranolol last week on Thursday by the doctor as I thought it may be anxiety. I have been taking this as it states on instructions but it doesn't seem like my symptoms are disappearing. It is keeping me awake all night, for many nights. I have recently thought it could be something gastroenterology-related, which is what I most convinced at the moment. I had a bout of hiccups yesterday, but of course this could have been nothing. My body has been making a really strange gargling noise after food sometimes, in the lower right quadrant area near where my appendix is. Please help. Catherine.
