For the last two years I have been very ill from the effects of my computer. My Samsung phone and Samsung tablet.
My symptoms are as follows: After 10 - 20 minutes I begin to get a VERY bad headache. After 30 minutes my heart beat becomes very irregular. If I continue for another 30 minutes I get very sharp pains all over my body from head to toes.
My girlfriend has a shieldite pendant and she gave it to me to try and I experienced a 50% decrease in my symptoms."
