I've only had it a few days, but it's stopping me from sleeping! If I breathe in slightly too much, I end up coughing and spluttering. I can taste blood sometimes if I cough too hard and it feels like something's being torn in my chest. Not quite like that, but that's the best way I can describe it. It's come from a cold earlier this week. When I had a shower yesterday and inhaled the steam, it went away for about an hour but now it's back in full force. Anybody got any tips to ease it? I'm going insane!
