I am suffering from sciatic nerve pain for about 5 to 6 years. It recurs in every 3 months time. At the most serious time, I need to rest for every 3 steps of moving and it took me more than 15 minutes for going to washroom. Only if you have this problem or you will not understand how we suffer! Ever since I wear the BIOFirion® necklace, condition improved! Now I can sit in front of computer for 6 hours and not feeling pain, last time the pain will come when I sit for one hour. Thanks to BIOFirion®!
