I don't know how you're managing sticking your fingers down your throat and typing at the same time. Just because arnica (non-homeopathic, 'we waved some arnica at it from across the room' non-concentrations) can cause bad things doesn't mean it will.

Ibuprofen isn't addictive and it's an anti-inflammatory, which means it actually helps heal and doesn't simply mask the pain. If you take it with food and your stomach doesn't complain, it's not a bad thing to keep taking it. Check with your doctor though.

('Arnica' - what does YOUR spell checker tell you you should use instead?)
