I went to the doctor yesterday. They ordered lab work to test my thyroid and b12 levels. Sent me home with some vitamin b12. It hasn't helped at all. My face/tongue/arms/hands and feet are still constantly tingling. My neck and lower back hurt. The lower back pain wraps around to my groin and into my knees. Woke up today with my hands and arms burning and feeling extremely heavy. I feel like my doctor isn't listening to me. I feel like no one is listening. I've been in tears all day. What is wrong with me? I can't handle this.
