Dr says i have gerd but can't stop thinking it's my lung. I don't have heartburn or stomach pains really which i thought you had with acid. I keep waking up in the middle of the night feeling sick and sweating and then can't get back to sleep. I keep feeling my breathing is restricted in the bottom of my neck. When i sniff or cough i have sharp pains up the right side of my neck and right shoulder and back ache. I have no appetite and have to force myself to eat and feel shattered. Why can't i trust my doctor and blood tests? I just keep thinking i forgot to say this or that to the doctor so they will miss something.
