Coaching for medical issues

Hi Brooke, I’m interested in coaching people with chronic migraine. I can’t promise to eliminate migraine but my program would help clients reduce the negative impact of migraine in their lives.
My first question is, is there a legal risk associated with coaching around a medical issue if I’m not medically trained?
My second question is, given I likely couldn’t get into your coach training until 2019 could I just start now so that I had some experience before I come to training? Do you think it’s reasonable to coach with no coach training if I’m confident I can help?
