i M NOT SURE WHAT IS MY PROBLEM.a WEEK AGO i WOKE IN MIDDLE OF NIGHT AND STARTED TO THE BATHROOM,BUT WAS SUDDENLY VERY WEAK IN MY LEGS AND FELT LIKE i MIGHT FALL DOWN. i LAID THE TOP HALF OF MY BODY ON THE BED BECAUSE THE BED IS HIGH AND DIDN T FEEL STRONG ENOUGH TO CLIME BACK UP ON BED. aFTER A LITTLE WHILE i DID GO TO BATHROOM AND WALKED BACK TO BEDROOM. i DIDN T GET BACK TO SLEEP FOR QUITE A WHILE. iN THE MORNING i FELT EXHAUSTED AND HAVE FELT THAT WAY EVER SINCE. i HAVE BEEN DOING A LOT OF HARD WORK PAINTING AND MOVING FURNITURE. i SOMETIMES FEEL LIKE i HAVE A TEMP AND i AM FLUSHED. i AM 72 SOON TO BE 73. i AM DIABETIC AND HAVE SLEEP APNEA. i DON T KNOWS WHAT COULD BE THE MATTER.
