Desperate for help !

[kyhusband]

My wife has been passing out several times a week for over a year now. She has seen two different cardiologists ( one was a Electrophisiologist) and two different nurologists. She has had MRI, MRA, Cat Scan, ECG, EEG, TEE, EKG, Complete blood work up,Blood gases , slight low level of glucose with the Fasting glucose tolerance test, tests in the mid-high normal range for thryoid,
Symptoms are feeling of the spins moments before going unconcious. Sometimes numbness and tingling in extremities before passing out can occur or feeling hot/flushed before hand. Sometimes all the symptoms before passing out. Unconcisness can last for up to 45 seconds with twitching as she regains consciousness followed by a severe headache of a 10 on a scale of 1-10. While hospitialized, morphine and or Demerol was used to treat headache pain and found no relief from Morphine, but relief from the Demerol. Tilt table tests show very little change in BP or pulse while going unconcious.Also tested Arterial pressure while doing the tilt table test. No one can figure out what is wrong with her or how to treat her. HELP us please !!
