I have, like many others so I see, have been trying to figure out what is wrong with me for about 5 years.  I began with digestive symtoms, numbness and tingling and increasingly worse depression and had all the (GI) tests they knew of to do EGD, colonoscopy, barium swallow, & vials of blood work.  I had also mentioned the numbness and tingling to my internist and gastroenterologist.  It was always blown off as a seperate issue-lets figure out what this stomache problem is first-or one thing at a time dear.    As an ICU nurse for many years I frequently saw patients with multiple problems where their docs would only look at their "Part" and not the whole picture and group of symptoms.  This is how I felt.  The gastro. told me I had IBS.  So my internest had me see a new GI doc.  She redid the EGD and found only inflammation-no recommendation, nothing.  That was almost 3 years ago.  My health got markedly worse after I moved.  I had all the same symtoms but worse.  The numbness and tingling moved to my feet and arms instead of only my hands.  I was very depressed and extremely tired and foggy.  Not so good with 4 kids and a busy huband and no family around now for support.     Just last month, after seeing a new OBGYN for a yearly physical I was surprised when she wanted to check my Vit. D and especially surprised to see it was very low. ( I had put myself on 1000 IU's/day a year ago after watching Dr.Oz.)     My new OB prescribed 50,000 IU's/wk X 8 wks and I feel better-still not great, but less tired and foggy and thank heaven, less depressed.  (she had also prscribed Celexa that I took for 3 wks and quit because it made me so tired)   I continue to have the numbness and tingling but am hopeful that I can get that under control with a higher Vit. D level.    I'm grateful for this chance to tell my story and to have read others so similar to mine.  Best Regards to everyone!  You are always your own best advocate.   Suze
