For a week have been really tired, am followed by a Internal Med MD, felt really tired yesterday so went home from work at 3pm, went straight to bed but was restless, kept dozing on and off thinking I was dying. Post getting up, didn't feel as bad, but was standing at the sink, I felt a strange spasm, tingling, and burning type sensation starting below the umbilicus radiating upward extending thru the chest area and both arms, but stopping at the neck. Woke up again today very tired, I am having no GI symptoms, chest discomfort, BP and Blood Sugar is good. I am an RN. Just have never felt or heard of this strange sensation.
