What Causes Persistent Chest Pain With Dizziness?

Hi, may I answer your health queries right now ? Please type your query here...I have gone to the doctor plenty of times for the same problems. Its chest pain, majority wise on the right side at the end of my ribs. The first time they diagnosis me they told me I had a swelling of cartilage in my chest cavity causing pain. It went away for a week or so then got worse. The next time they told me I had anxiety and put me on depression medicine, the pain went away for a while but came back. I went again and they told me I had an infection on the lining of my lungs, called pleurlyis. The medicine is almost done and i STILL have chest pain. Now along with that I have dizziness, mostly occuring at night, it used to go away when I sit, and now it doesn t go away at all. I eat regularly, I have had my eyes checked and have 20/20 vision. Why am I still in pain. Every time I went to the doctor, it was for the same reason, and every time they tell me I have something else. I have a chest cave in and they are saying I need surgery on it, if so why is it happening when I am 18, and now out of all the years I have had it, they said it is pushing on my heart and liver..then why do I have pain on the right side?
