Sleep Apnea !!!!
Same symptoms as you+desoriented,extreme fatigue,weakness in limbs, feeling of bad circulation, ciatic pain,hot flashes from the pain,trouble with speech and putting two thoughts together, heart rate picks up even when sleeping,muscle spasms during sleep,blurred vision,different extreme pains almost every day. Lost train of thought from one second to the next.
Clean MRI and Cat scan, Vicoden helps somewhat and acupuncture does not last for long.
Tension in muscles all due to sleep deprivation.Check to see if other family members have been diagnosed.Worth looking into.Good Luck!
