I was fortunate enough to find some research about red light therapy for the pain and lumps of lymphedema. I bought the red light unit at Amazon.com for $40, the Pretika Lightsonic.
Imagine my surprise when I found that, in addition to helping the pain and swelling of lymphedema, that red light therapy also helps diabetic neuropathy. It takes away the pain and tingling in my toes, and stimulates circulation.
I use the red light for about 10 minutes on each set of toes, daily. My toes tingle after the treatment, and feel much better.
So, diabetic neuropathy can be helped a lot with red light therapy. And since the price is so reasonable, most people can afford it.
And, in using it for lymphedema, the lumps go away within 24 hours of treatment, so I treat my arm and breast area every other day. It takes me about 1 hour to go over all the swollen and lumpy parts. The light also kills pain within just a few minutes of use.
So, this is a universal help for those fighting neuropathy and/or lymphedema.
