Hi! Well I actually asked for the antibiotics. I know that they only treat bacterial infections, but I have had this before, and it turned into Pleurisy, and was in hospital for 2 weeks. When I start to cough up yellowy green stuff, I know it's a chest infection and therefore does need antibiotics. I tried dealing with it before using only homeopathy and the green stuff turned brown. Then I couldn't breathe in. So, hospital. I asked for antibiotics in order to try and avoid that! Am still really breathless, coughing violently and nasty lungs. Not sure what else one can do!
