My son has had a cough for a couple of weeks now only during the night which disturbs his sleep but does not seem to bother him too much. Recently it has started to sound quite violent and this morning we woke up to find a dark red/brown mark on his sheet maybe around a £2 coin size. We put him down to sleep again tonight and the persistent cough is back and now a pea size light pink/red mark is on his sheet.
This is obviously making me worry however I'm unsure if I should take him to a&e the thing is tend to take him for everything as I never know if things can wait so really looking for some advice.
Thanks in advance! X
