Pulmonary and/or heart disease - your opinion?

I had a dear friend who answered a previous question (thanks). I am still a bit confused. Doctors said that my heart and lung is in good condition. I had: chest x-ray (airway and/or pulmonary hyperexpansion result), ultrasound (liver enlarged - otherwise normal), ct (mosaic attenuation pattern noted), another ct (airway disease resulting in mosaic perfusion).
I have pain (big) in my chest toward left side down to ribs, back pain mid and lower back on left side, lack of breath, tiredness, I sleep above normal, gain of weight, depression, swollen in various parts of my body including leg, feeling of shrink sensation on my left lung and spleen, left chest and abdomen cramp. My question?? Please give me your opinion? I need someone to give me some guidance so I can study and learn about my problems. It seems that Doctors are taking their time to draw blood and other tests but not conclusion is made other than say that it is muscle problem.

Thank you

you should go for a myocardial exert. AKA stress test just say stress test and they will be able to measure your breathing and see what is wrong with your pulmonary and cardiovascular system. also talk to your doctor about getting a VQ lung scan. are you having trouble breathing? it sounds like you need more than just a chest X-ray. find another clinition who knows what he/she is doing and seek for a second opinion.
