for almost 3 years although some began 7 years ago after the birth of my 3rd child. dizziness, unstable feeling, off balance, feelings of almost passing out, waves of naseau, heart palps, intense fear feelings, fuzzy head for hours at a time like I don't know where I am. shakinees, legs, stomach shakes, headaches. low blood sugar sometimes, heavy blankets of fatigue that just hit me. worse during my cycle! Tests: numerous blood panels, thyroid, Lupus, Hepatitis, AIDS, MRI 2 years ago, all Nero tests, sleep study, all ENT tests, cardio stress test/halter monitor for 24 hours, C Peptide, Vit B deff, iron deff, horomone panel, EPV, allergy food and airborne, several chest x rays, several EKGs. Here is what I know: I had Epstein Barr at some point in my life. I have Herpes Zoster that breaks out on my knee 2-3 times per year in times of heavy stress, I have low estrogen and progesterone, My MRI was clear with the exception of this: esentially negative enhanced MRI of the brain and internal auditory canals - a few non specific foci of increased signal are present within the brain parenchyma - what does that mean??? My chest xrays were clear except this: incidentally noted is aberrant right subclavian artery coursing posteriorly to the trachea - what does this mean and could it cause the symptoms I am having????? I have had 2 D-dimer tests done and one came back slightly elevated at 279 - that was in Dec 2008, not retested since. This is like a puzzle I cannot seem to put togehter but I know that is destroying my life because I don't feel well. I am 33 years old, 2 c sections, 1 natural birth, I weigh 135 pounds, 5'5". Past 2 years, not very active, I mean I don't exercise, I am going all day long and on my feet and never sit, but I don't exercise vigourosly. I can walk for days but as far as aerobics, I get dizzy and feel weird. Also, I should note that I don't sweat from my head, I sweat on my chest and stomach, a small bit, but not from my head.
