Oh Shropshirelass, I know how you feel. ABs should help and if pain meds not helping it could be trigeminal neuralgia. Can you get an emergency 🆘 dr appointment cos this pain is debilitating BUT sortable. A Google is not too scarey but will explain TN. Basically it’s 3 nerves (teeth, cheek and head I think) I’ve had it for 6 years now after being sure it was dental eventually went to dr. I’m on an epilepsy pill 3 x daily, a friend who also has it is on amitriptyline. Keep taking the pills and pain goes, miss a couple of days and it comes back 🥵.
Thinking of you but insist on getting seen ASAP, CLKD’s advice should help to tide you over 🤗
