Some days ago i posted about my B12 levels(214pg/ml). I am sure that i was deficient since i was having these unexplained pains mostly in my chest(Now gone with supplementation). I had vitamin D deficiency which is at good levels due to supplementation.
My Thyroid levels are normal (TSH is 0.54 which is nearly normal).
No lung problems.
I have nasal allergy but no Asthma.
I have this unexplained productive cough which is always mild only. Though i stopped smoking 3 months back . Done all kinds of test but no apparent reason. This phlegm just comes below my Larynx and i have to cough it out. Some time i feel difficulty breathing too. There is no color just white.
Before i start immunotherapy i have to rule out if there is anything causing this cough except Allergy.(Like thyroid or Larynx)
Can B12 deficiency cause productive cough? I know it can cause nerve damage in Larynx but then cough should not be productive. Has anyone experienced this kind of Mystery.
