above the neck; sweat it out. Below the neck take it easy.
Sounds very familiar, I've had asthma off and on for 25 years with no attackes since the early days which led to the diagnosis.
Last 2 years, 3 chest infections which twice ended up as 'mild' pneumonia (jeez knows what proper pneumonia feels like – I'd cough until I didn't think I would ever get another breath in and walking upstairs left me so breathless I'd need to sit down). Both times started off as coughs / colds that I just didn't shrug off. I don't know what's changed although since having had my drug regime modified (touch wood) I've been better. But this swine flu does worry me; 3 years ago I'd have thought that a week of feeling shitty and then better was no big deal, now I'm not certain how well I'd cope.
Take it easy and get well.
