For the last 3 years I have been experiencing bone pain, headaches, kidney pain, heart palpitations, dizziness, and in able to loose weight no matter how much I exercise. I have had my thyroid checked and it jumps from normal to low and my vit d is slightly low. I have been taking 1000iu of vit d and it has been causing me to feel sick. Every time I ask my doctor to check my parathyroid she finds every excuse why she won t. I know something is wrong with my body. I don t feel right. I need to know its not all in my head.
