Left lung problem??? help please!!!?

Okay, so I suffered a bleb busting on my right lung two months ago and had surgery a month ago. They did the talcum powder operation. I forgot the name of it. Anyways, recently I have been having pain in my LEFT lung. So today I was sitting around, in a little bit of pain and having trouble breathing. Then I went and help my dad load his truck with watermelons. We loaded fithy and when I got done both my right and left arms from elbow down were numb and also my face. Plus it was even more difficult to breathe. I used my inhaler but it did not help. So I went to the hospital. They took my right back. My blood pressure was not good. They didn't tell me if it was low or high though. The numbness had gone away but I still had problems breathing. Instead of going to do xrays right away... they waited and hour and a half. Then when they took the xrays, I'm not sure because I'm not a doctor, but I think they took them wrong. First they took them from the back... THEN, they took them from my RIGHT side, not my left. And my left side is the one giving me problems remember? SO if it is my left lung, shouldn't they take the xray from my left side??? That and they said they compared the xrays to my last ones in may... which was also facing my back and right side. So, they told me I had inflamation from the surgery and my chest wall was expanding. And gave me moltrin... that was their diagnosis. Now, I am at home about 45 minutes after that... and my left arm still goes numb especially with me typing right now, and my left lung hurts in the lower portion of my back and ribs and in the chest area... on the LEFT SIDE... but my right lung doesnt hurt at all. If it was inflamation from the surgery.. shouldn't my right lung hurt before my left? Breathing is alright.... but still a little difficult, not nearly as hard as it use to be. Please help. i am 17, I have a heart murmur, was born with a pin sized whole in my heart and don't know if it has closed up though the doctors said it should have by now, I have asthma, allergies, and remember a RIGHT collapsed lung do to a bleb erruction. Need anymore information please let me know. I am quite worried right now.
