Until recently, I had never treated corns. All I knew was they were painful. Bu after palpating a couple, I knew I had an effective treatment for them. They gelt squishy on the surface with a hard spot deeper. So I thought inflammation and calcium buildup. Since inflammation can cause calcium deposition, I thought I was on the right track with my diagnosis. So I used my Anti-Inflammation Electro-Acupuncture (AIEAC) treatment on them. Just one needle on both ones I treated on the first treatment.Since they were both between her toes I ran it for 30 minutes on each one. The next day she reported the smallest one had already disappeared. The second one had shrunk in size.A week later she had another treatment and that one disappeared as well. The third visit she showed me a third one that was larger than the other two and was in a harder place to get at. So I treated that one the same way.But being larger, it took three treatments to get rid of it.
