Is it at all possible you have celiac disease?

Most often it's a gut issue, but it has neuro and pain varieties. (I get ringing in my ears, dizzyness, tingly hand and foot, odd pains, and used to get rashy-stuff on my hands and feet; along with a host of gut problems. I feel like a damm hypochondriac half the time!)

Celiac messes with the body's serotonin levels and knocks the serotonin transport molecules out of commission. Leads to depression and other serotonin related problems (OCD, panic attacks, etc) and nerves that over-react to stimuli. Oddly enough, the use-able serotonin improves in celaickers who are chronic smokers, the nicotine helps.)

Since celiackers can't absorb nutrients properly they can have wide range of nutrition issues. Vitamin B12 is a biggie (thats a vit that's very important for the nerves and very hard to absorb. Even taking 160x the daily amount, my blood level is just barely normal.)

Celiac can be quiet most of the time and just blow up suddenly from stress, too. Mine defintely gets crazy sometimes and has been non-existant other times.

My old doc was convinced I had MS for 2 years, until I finally went to a couple neurologists and they both thought I was dealing with celiac related stuff.

It might be worth looking into. (mind you, take all this with a grain of salt. but if you're curious it might be worth a half hour on google)
