Ok so I've had a really chesty cough for a couple of weeks now, when I cough it really hurts the centre of my chest. Sometimes I can cough stuff up, sometimes it won't release so rattles on my chest. I just wondered how I would know it was a chest infection or not?
Also, when I can check my PF its around 420 (PB 550). I just wondered, I've read people with asthma should see their GP if they have a chest infection, why is this? Does it take longer to clear? Can it get worse? I always get coughs like this but have always let it run its course but don't know if thats the best thing?
