I am glad you are being a good medical consumer. This is your life and your body...you need to ask questions, understand and have a say in what the treatment plan or options are. The days of the doctor being God are gone or should be gone. Beleive me, just like in any other profession, thee are talented and good one and there are so/so docs. Be educated and continue to ask away. You are just the kind of patient I like. I am glad my explanation helped....<br />

Robert... an abdominal ultrasound is not invasive.  Looks like the docs may have ruled out cardiac since all your studies were normal- so they are looking for another cause to your problem. Sometimes pain is referred from another area. The ultrasound will tell them what is going on- probably looking at gallbladder. The test involves the sonographer rubbing some gel on your abdomen and then placing a transducer (looks like a micrphone) over your abdomen at different angles picking up the pattern of sound waves to creat an image. No needles- just pictures. You may be asked to fast.  Good luck .i know it is really tough going thru the testing process... the waiting and the not knowing is so stressful. Sometimes it takes time to rule out some things before you move on to a possible second cause to a particular symptom.  i am sure they will find an answer.   :smiley: <br />
