I'm a 18 year old male and Back in march my whole body went numb. It took about 4-6 hours for it to go away.that same day at about 12am my body went numb again! then the next few days different parts of my body would go numb. I've gone to my doctor he didn't know what it was, so he sent me to a Neurology expert, and even he didn't know.
In July I went in for 2 MRI scans one of my head and one of my lower back. they said they could not see anything wrong. Now about about a month ago my left foot at the bottom of the heel and down the bottom left of my foot is numb. Just 30 minutes ago my body went numb again...
But it seems to have stopped. this has freaked my out a lot... I don't do drugs or drink, or anything like that. if anyone has any info please share. (sorry for any bad grammar,spelling,etc its 3am here)
This is a truly odd set of circumstances. It is easy to see why your physicians are baffled.
It is unusual for the whole body, from the top of the head to the tip of the toes, to do numb, without the loss of consciousness or developing any weakness.
That would mean that something is selectively affecting the two strips of sensory cortex, but not affecting anything else in the brain.
And, then, to affect specific dermatomes or areas innervated by a peripheral nerve. So, the condition has shifted from a central nervous system to the peripheral nervous system. A single lesion could not do such a thing. Does this mean that you have multiple lesions, which only sporadically cause problems? This is very odd, but interesting.
It is often taught, that when things don't make sense from a neuroanatomy standpoint, that the patient should be evaluated for multiple sclerosis (MS). But, the lesions from MS in the brain should have been picked up by the MRIs. It is true that the MRIs may have missed the lesions, and in that case an LP (lumbar puncture, spinal tap) would have to be done. But, still, the symptoms you mention would be very odd, even for MS.
This is something that is probably going to take some time and multiple visits to determine exactly what is going on. Access to medical care is much better now days, so patients are presenting at earlier and earlier stages of disorders, before the "classic" signs and symptoms have had time to develop and present themselves. So, it may be that, whatever you have, just has not had time to show all of its signs/symptoms.
You might want to keep a small journal on your symptoms. Jot down exactly whatever happens, when it happens, what were you doing at the time, how long did it last, any other symptoms that appear, and what you did to help make the symptoms go sway. Often, a diagnosis depends upon seeing a pattern in the symptoms, that points to a specific disorder.
You may have to see your physician several times or even see several specialists, before someone has an "Aha moment". So, you are going to have to be persistent.
Good luck. If you do find out what is causing your problems, please let us know, so other members can benefit from the information. Again, good luck.
