Lung Nodule, D-Dimer elevation and ANA +VE:

Do I have LUPUS?
In June during my India trip left side Ribs pain started when breathing.I returned to US on July 5th and next day I visited primary care, he ordered CMP and X-RAY both are normal.nothing shown in the X-RAY.After 2 weeks I visited primary care again, then he checked EKG, it was normal.In my 3rd visit Primary care ordered bone scan which gave some clue about pleural effusion.After that i visited Pulomonologist, he checked ANA which came +VE,D-Dimer elevated(high).Then Pulomonologist ordered CT scan in which identified a patchy nodule, by this time pain was severe, lots of burping and incomplete yawning. For small burping and yawing back was hurting a lot.

After nodule identified in the lung, doctor put me on LEVOFLOXACIN for one week then pain got controlled.I finished medication on 09/27, after 10 days ribs pain started again. I am 47 yrs old,hypothyroid patient,previously i was diagnosed with Fibromyalgia (since 2010).These things are scaring me and making me sleepless. Need advise.
