All other reports are fine... I hv no symptoms, but sometime i feel diffculty in breathing , its only when i m resting,may be i m thinking too much about this ., There is no any other prob, like cough, dyspenia, weight loss ., my doctor suggested me tab montek lc , and tab septallin ( himalya ayurvedic product) my doctor belongs to india.. I just wanna ask these fibrotic bands could be dangerous . I m so scared .. Plz tell me whats that
