I am new to this community. My mom is suffering from some peculiar lungs disorder and doctors are not able to diagnose her.
Symptoms
1. shortness of breath at rest
2. cough with whitish sputum
3. fever which feels but not detectable by thermometer
4. fatigue
Light symptoms appeared 3 months ago which deteriorated to oxygen dependency within two months
Following tests have performed so far with no diagnosis
1 . X ray
2. CT scan chest
3. Tuberculosis test (negative )
4. pulmonary function test.
5 CRP
6. ESR
7. Broncoscopy
8. ABG
9. CBC
10. RFT
11. LDH
12. USG abdomin
All the above tests are inconclusive and do not provide any clue.
Anyone can please suggest something additional which might help in diagnosis
