1: for months now when ever I cough ( even a gentel cough) I taste blood "iron" in my throat

2: when ever I laugh I start coughing and not gently

3: I have so much trouble breathing even more so after a Coughing fit

4: I have been sneezing a lot more than normal for anyone but I have no allergies

I have never smoked , I don't drink but I am a large women 15 stone 5 foot 3 inch and I work at my computer as an artist but I go out biking daily

I have gone to my doc's as I also get heart problems they have done blood tests and other things but nothing has come up
