So as usual it's the summer, there's lots of grass pollen about (I'm ridiculously allergic) and my hayfever is a nightmare. Unfortunately if affects my asthma something rotten which isn't anything new, it's done it the past 2 years. I've just got some singulair prescribed so that should hopefully kick in soon - miracle drug! Anyway my question is - my asthma is more of the cough variety than a wheeze. Lately sometimes when I've coughed the back of my throat has tasted like metal, it tastes disgusting. I'm fairly sure I'm not actually coughing up blood cause theres none on the tissue/my hand./whatever I've put to my mouth when I've coughed but what could it be? I've googled and most the results point to an infection but I'm not sure, has anybody else had this? I just hope my singulair kicks in quick, I am so uncomfortable. Feel tight chested and starting coughing up a lung anytime I step outside.
