I decided to visit the doctor on Monday, got an appointment for the next day.
The doctor stethoscoped me, peered down my throat, checked my blood oxygenation. She prescribed Doxycycline antibiotics (they must be good, the leaflet says they'll even cure syphylis, which I've always considered to be the Queen of STDs), and an inhaler, and a puffer of Ventolin, to ease my in-throat congestion.
The cost, of course, was zero.
I cannot understand why the Americans aren't demanding a similar system - paid for out of taxation, free at point of delivery.
