I've got a horrific cold with a bad chesty cough. It's completely wiped me out and I've got no energy at all. I can barely get through the day. It's the chesty cough that I'm wondering about though. DP and DD both have the same cold but their coughs are clearing up and becoming drier. Mine is still very chesty and productive (haven't looked what colour or anything ) and I'm finding it quite tough to breathe. It's like my body is struggling to find the energy to expand my lungs. I'm not wheezing or anything. Is this just part of the cold or should I watch it? When should I go to the docs with it? TIA.
