I circled my shoulder with a Big Bertha and the gym shoulder strain should have lasted 2 weeks but it lasted 2 days.
Also i have it in my pocket going through London and it feels like it blocks out any bad energy, i dont feel exhausted going through a busy city anymore. Perhaps placebo, perhaps genuine. I went without it through London the other day and had tiredness and negative thoughts, so I think it does block out others negative energy. I think this is very healing for chakras too. So theres another world to explore there with healing the aura and chakras with these magnets.
