question: Hi, I have just had a full heart check and got the all clear.  Thyroid okay too.  The reason for the test is that I a exhausted after doing physical housework and get very breathless and wanted to know if I was just unfit and overweight.  I have always suffered from allery and allergic asthma.  I have had a lot of heartburn recently (which I had a gastroscopy) a few years ago.  I still have a dry tickle where I want to cough (it's only a little cough) and tightness in the chest area.  Do you think this is just asthma or related to nasal drip? My blood pressure has gone up a bit and so has my cholesterol (5.7).  I am on Zoloft, Karvezide 300mg and Phototens.
