just a shot in the dark, but I was reading about alot of women who had breast implants,not silicone but saline. the shell of the saline implants are made of silicone. They had symptoms such as severe everyday headaches, neck stiffness,shoulder and upper back pain. they had heart palpitations, which I have,leg muscle twitching,extremeley cold hands and feet.also hair loss, which I also have. They say the silicone attacks the immune system. Some doctors agree and other doctors do not believe implants can cause these problems.One women said she had severe debilitating headaches. Since she had them removed they have become less frequent. I have seen specials on tv about women with these kind of problems and once they had them removed they slowly got better. I amwriting this because I have saline implants since May of 2005. Everything started in July of 2006. This really makes me wonder. Anyone out there have saline implants and get headaches, or any other systems.
