Hi been diagnosed with COPD for over a year now. I had flu like illness week before Xmas and chest infection. Chest pain mainly on right side. I have had 3 lots of anti biotics and an x-ray which has come back clear ? I do have osteoarthritis and fybromyalgia which could explain the pain. I am confused at why I'm still bringing up tiny bits of thick sticky yuck ? I have no idea where to go from here ? Can anyone suggest or help please. Many thanks.
