Are my pains caused by anxiety?

Around February this year I had really bad pains in my right lung that would throb whenever I inhaled deeply or exhale slowly. I went to the doctors and to the hospital about it because the pain worsened over time. The hospital reckoned it was a chest infection and gave me pills to clear it up. After a week the pain went away.

But I’m noticing that every now and then I’m experiencing the lung pains. It occurs a few times and then goes away. I just ignored it though.

The other day I had a panic attack enduced by the pains that I had been feeling all day. My college phoned for paramedics and they checked me over three times. They checked my pulse, blood pressure, blood, oxygen intake, lungs, and even my legs! But they couldn’t find anything wrong with me. My doctor didn’t understand what was wrong with me either, back in February when the pains started. The paramedics suggested I should go back to my doctor to investigate. They also said the pains could be brought on by anxiety or stress.

And I don’t know if they’re right. I mean, the other day I was on the bus thinking about college (I still get a bit nervous about going) and the lung pains came back.

I just feel really helpless because nobody seems to know the real cause of these pains. :(
