hi all, I need someone to share my anxieties with, a shoulder to lean on if that's ok.Diagnosed with copd afew years ago , I go through the usual chest infections each winter but never needed hospital. This time the antibiotics aren't working nor the steroids and I feel weaker and more ill than ever. My GP is puzzled because my blood oxygen is 99 percent and blood tests all clear. I have had scans heart tests and numerous x rays nothing ever shows. I can't do a thing without starting to choke and cough. Anyone else had symptoms like these?
