I had silicone unders for 18 months. After 8 months I developed full blown autoimmune diseases. Allergies, Chronic Fatigue, brain fog, Candidias, muscle aches, numbness in my extremities, skin deterioration, loss of hair. Prior to the implants I suffered mildly from psoriasis.
If you have a history of auto immune issues, any rheumatoid problems, silicone will push you over the edge into a minefield of health issues.
I am explanted 3 months and most of my symptoms have gone.
