Hi, and welcome! Many of us have been told it's all in our heads...even some of our doctors have said that, so you are not a lone.
Check out Fibro 101...the first thread on the forum. There are links to good information about fibro and you will learn a lot there. There is a link to a list of symptoms. You just might "see" yourself there. There is also a link called What Else Could It Be. These are other illnesses that have many of the same symptoms of fibro. A good doctor runs a battery of tests to rule these out before a diagnosis of fibro is given.
I have similar chest pains. I have what is called costochondritis. There is a link in Fibro 101 all about that, too. You might want to read this and see if it sounds like what you are going through.
You see, not all doctors believe in this illness even though it is recognized by the National Institute of Health, the American College of Rheumatology, and the American Medical Association to name a few. You need a doctor that treats fibro patients so, if you do have fibro, you can get help. Talk to your parents about this. Many here use a rheumatologist but I use a board certified Internist as my doctor.
It sure isn't fun having these problems and no one listens. We have been there. I hope you and your parents can work together to find what really is going on with you. Please let us know what you find out because we really do care about you.
I'm glad you joined us and I hope to hear from you soon.
