I know this is not really a medical forum but it's the most active one I'm a member of. I've recently acquired a bad cough that got worse when I went into work yesterday. I keep waking up and last night I woke up coughing and unable to breath due to mucus blocking my airways completely I had to force myself to try and throw up to breath. I've been unable to contact my GP and have only expired amoxicillin and a tiny bit of cough syrup left. Does anyone have any advice to help as I'm really not sure what over the counter treatments I should purchase and my GP is only open for an hour today so getting an on the spot appointment may be impossible.
