So glad you finally got to see your GP and have started the meds. Hope you feel better soon.
My GP directs calls to the out of hours service outside normal surgery times. This can be at my own GPs practice are a different one in the area. Doesn't your GP provide a similar service?
Take things easy until your medication kicks in TOB. Stay warm , drink lots of fluids, eat what you fancy. If you deteriorate contact family again for assistance . Good luck .
