Sorry to hear of the breakage, that's an awkward one indeed. Hard not to be in pain or discomfort with it too.
Be careful with your stomach if you're taking those pills for more than a day or so.
Make sure you eat with the ibuprofen, and joking aside, eat roughage too !
Tbh, it's not really a good idea to mix the potions of the pharmacist with home herbal cures. Too easy to get too much of something or to dilute the value of what you're taking.
That said, and you're a practical sort and not likely to go and do something daft....
Broch's advice on the comfrey is good
Meadowsweet is also good, but it's only just in leaf just now. Flourish comes later, and if you haven't sussed out where it grows it's hard to find the roots. Willow bark was traditionally used too. Find the goat willow though, it's an awful lot nicer to chew than the bitter/bitter of the other varieties.
Turmeric is supposedly good for inflammation and pain as well. Vitamin C and if you're a meat eater, make bone broth and drink it like soup daily.
