Okay, so my pregnant girlfriend is in hospital now. She went there BC she had bad cough that wouldn't go away after continuous antibiotics for a "sinus infection". Well she received a chest x ray. And a perfect clear circle 9cm BIG appeared in her left lung. They have her in isolation in case of TB and are waiting for TB test results before deciding what to do. She shows no TB symptoms.. More so symptoms of pneumonia.. I'm freaking out here.. Any clue what's wrong. Dr.'s here in hospital are giving no answers really.. Kinda leaving us in the dark
