I agree with GM arnica will help greatly with past injury never well since. had a great healing take place with a woman injured 20 yrs ago in a skiing accident her shin bones were damaged. for 20 yrs she had extreme pain, tryd all types of conventional painkillers. ( she is a allopatic doctor ) her pains were so bad at night she lost sleep. only one dose of arnica 200c helped the following day. A year later return of symptoms I gave her arnica 1M one dose. thats it amazing!!!!!!!no more pain.
