I was diagnosed with Hashis and PA a month ago. I was started on 2 grains of NDT and 5mg B12 sublingual as well as B6, a multivitamin, reacted iron, DHEA and progesterone. I was already on 10,000IU of Vitamin D daily. Before my diagnosis I was getting these horrible muscle spasm headaches that would send me to the hospital. When I first started the NDT and B12 they got better, but now they are getting worse again. My doctor does not have me scheduled until next month to check my levels and possibly raise my dosage. These headaches are killing me.
