Apple Cider Vinegar, Arnica for Joint Pain

I suffer, as most, from occasional joint pain/inflammation. The other morning my neck was severely inflamed, limited motion. I took a cloth dampened it with warm water then some ACV and almost immediately felt improvement. There may be slight discomfort, this is temporary. I would also like to suggest arnica cream. This greatly improved jaw function after surgery and is a great source of minerals necessary to healing injuries. May God bless.
