I have a heavy cold and a cough, had it since the w/e. Throat is sore, now chest is sore too (all the time, but particularly sore when I cough). I feel like I have a heavy weight pressing on my chest. Not breathless atm but then I haven't walked anywhere today as I feel so rubbish. Can't talk without coughing. Never had a chest infection so nothing to compare it to; is this likely?
