I've had a chesty cough all week. Coped ok at first (3dc to look after so kept going as you do) despite off/on fever chills etc. Have spent the weekend mainly in bed trying to throw it off but now worried it's a chest infection. When I cough I'm getting a weird cracking/fizzing in the back of my throat . Should I bother the GP with this tomorrow or am I over thinking this and just need a few days more rest?
