OP, Are you able to swallow, take fluids, are you passing urine?
If so, keep up fluids, ice lollies are good, soluble aspirin 300mg, 4-6 hourly, gargle and swallow; NB. Do not take soluble Aspirin with Ibuprofen...but you can take Paracetamol with it, assuming you have no contraindications to taking anti-inflammatories, ie elderly, renal impairment, gastric issues...
If you start drooling, straight to A&E. Quinsey is uncommon but can occur.
What is your temperature?
10 days on, it should be starting to improve on the back of Penicillin and clarithro'
Best of luck, so, so grim. X
