pernicious anemia and B12 overdose

I have pernicious anemia and get injections monthly.   i was given a B Complex to take which contained B12 in it, without my knowledge (my stomach can not absorb or break down B12, reason for the injections).  i took the B complex for a period of two months and became severely ill with vomiting/diahrrea and the inability to keep anything in my system.  On may 26, 2008 i was sent to the hospital by ambulance (don't recall anything about it) and was told that i was completely dehydrated and lacked oxygen.  they said that if i went thru the ER via the waiting room...i would have died.  since then, i have been experiencing great pain with muscle spasms that are so severe, my whole body trembles.  i clench my teeth because of the pain, and have already lost 3 teeth, 2 root canals and chipped my front tooth.  I have had, for many years, upper body pain due to fibromyalgia/chronic miofacial disorder yet had no problems with my legs.  i am unable to walk (with any speed...old people walk by me!), travel ANY distance without severe pain, spasms and the inability to sit or stand for any extended period of time.  Could the B Complex that was given me be the cause for my lower body problems i currently have?  (fyi: i have had PT, and many other treatments to try to help, unsuccessfully.)
