My son, now age 14, has been diagnosed with Tourette's since age 5 when he began with eye blinking, neck twisting and diaphraphatic movements/"huffing". Along with these has been an abdominal "cold, electric" feeling. His eye/neck/"huffing" is much better these days, but the abdominal sensation is much worse. He also feels as if his diaphram area is always "tense". He is on a very limited diet these days, as sugar, grease, artificial ingredients and soda pop made this abdominal sensation unbearable. My son often does many sit-ups in order to help relieve this sensation, with limited relief. I'm wondering if anyone else has experienced this type of a sensory tic and what they did to help the situation. Currently my son is taking Tenex and supplements with B vitamins/grape seed/Magnesium Taurate and fish oil. I'd appreciate any suggestions!
