Lung Pain for 3 months

I am a 39yr female in general good health with no real medical issues.  I have had a knee replacement 3yrs ago and a hysterectomy now 12 yrs ago.  About the 15th August I started having a very dry cough without producing and sputum/phelm.  I would lay down for the night and not be able to sleep on my right side without screaming due to the pain. 9/10 pain scale when lying on my side, however I couldn't lay in another position because it would become 10/10 pain scale due to the addedpressure on my right lung.  The pain was throughout the day only in my lower right lung.  No falls or any other trauma. Finally, in the middle of the night I thought I was going to die.  Literally, the pain decreased my breathing so much so I went to the hospital.  

A CT contrast scan was performed and the results showed NO PE however my D Dimer was 1115 out of range of normal.  My CBC showed and elevated white count and nothing to note with the other testing. The ER doc stated that I did NOT have phennoma or broncitis, but there is something wrong with my lung.  They administered Tordol due to my allergies to Morphine, demerol, and the Caine family.  I was able to breathe a little better but the pain was very much still there.  However,a month later another radiologist upon a second CT contrast found and I quote these finding (the exact findings as the first CT scan).

Findings:  There is a small pleural fluid collection.  Overlying this area is a small amount of dependant or compressive atelectasis.  There is an associated nodular density at the right lung base.  This measures 1.2cm in diameter but has attenuation values measuring between 5 to 10 llounsfield units consistant with loculated component of pleural fluid.  This may represent filling of a pheumatocce or other pre-existing cystic cavity in the lung.  A densely calcified granuloma is identified at the right posterior lung base measuring 4mm in diameter consistent with prior granulomatous infection.  No areas of parenchymal consolidation are identified.  The heart is normal.  The thoracic aorta is normal in caliber & enhances normally.  No hiliar or mediastinal lymphadenopathy is identified.  
Impression:  There is a small right pleural effusion as well as a small focal fluid collection identified within the lung parenchymal at the right base.  No solid pulmonary nodule or mass is identified. No evidence of parenchymal consolidation is seen.
Question:  What is this and why am I not getting better?  I have been on 10 days of Leviquin without relief and Augmentin with calcium still without getting better.  I am really tired of the pain, the SOB, the agony in the night is the worst.  WHAT IS THIS?  When I breathe I can not obtain a full breath because when I do I feel like there is an ice pick in my lung.  I tire very easily, I don't feel well at all and yet there is no phelm with this cough and yet I must use a pillow to get a cough.  

How and what do I do? Could this be lung cancer? Should I obtain a biopsy?  What do I do?  
I am currently taking Climara (HRT) and Advil only help to reduce my pain level to 8/10.  My PCP says that he is stumped with this and he's run out of options.  Do you have any suggestions to make this go away?  Could this be Mesophiliomoa?
Please help.  Thank you for your personal consideration and time. Respectfully, HS
