With severe cold, cough, sneezing, weakness, chest congestion since months, I tend to cough out mild yellowish blobs of cough each morning & sometimes there's blood too. I am a 27 year old femae. I had started taking 4 Septillin tablets each day (2 after each meal). I got better as summers arrived but symptoms have neither alleviated nor reduced. I had stopped taking Septillin for about 2 weeks during these 4 months. Does stopping it works like allopathic antibiotics? Are these TB symptoms?
