A little tip that helped me two weeks ago when I was feeling very ill with the flu. My legs were hurting big time so after dinner I made a hot footbath with nigari (the only kind of magnesium chloride we can get). Amazing, while before it felt like someone was cutting my legs off and my head was also feeling weird right afterwards I had no more discomfort. Worth trying..... I knew that a hot footbath can cure a headache because it pulls the blood away from the head and in this case it relieved me big time!
