My 7 year old son has started blinking and shrugging his shoulders few weeks back. I started him on magnesium taurate and b vitamins. Sometimes he takes Epsom salt baths. I give him flax oil on and off, I recently noticed that his skin around the genitals area has turned very dark. I don't know for how long it has been like this and if this is normal. Sometimes, I have seen him scratch there so maybe it is itching. But when I ask him, he says he is fine. I am still in the process of reading as much as possible to educate myself. My husband had facial tics when he was in middle school for a couple of years. But he doesn't do it anymore. So there is definitely a genetic component involved. Do you of you know if this is some kind of infection that could be related to tics. We live in a small town and the pediatrician just said that my son has a tics and that it will pass with time.
