Hand and foot pain, cramping and muscle twitching after stopping Seroquel

[KingKateKong]

I was on 600-900MG of Seroquel for at least 5 years.  I contacted my psychiatrist about stopping the medication when I realized it had been prescribed for a condition I do not have.  My doctor was not open to this conversation and I unwisely decided to stop on my own.  I did a fair amount of research prior to my titration and even went so far as to map out my titration schedule on a calendar.  My main withdrawal concerns were anxiety, rapid heart beat and insomnia.  After a few days of titration when I realized I was not having ANY withdrawal effects I basically stopped "cold turkey."  About two weeks, after stopping, I experienced a weird cramping sensation in my hand.  Based upon my rigorous physical activity, I assumed I was dehydrated.  The symptoms persisted for a few days and I decided to see a doctor.  My labs ruled out an electrolyte imbalance, but I decided to start a daily calcium and multivitamin regimen at the recommendation of the doctor anyhow.  For the past month, my symptoms have gotten out of control.  I have had burning, pins and needles, tingling, numbness and cramping in both hands and feet.  I recently (in the past few days) have started to experience muscle twitches in both legs.  I have seen a primary care physician and a neurologist.  Between the two of them, I have had numerous labs and they are ALL normal...electrolytes good, no vitamin deficiencies, liver/kidneys good, thyroid good, no rheumatoid arthritis, no muscle wasting and I seemed to pass the in-office neurological exam.  I feel like my electrical system has been misfiring for weeks.   Every day it is something different--sometimes painful, sometimes annoying, sometimes both and never, in the past month, have I been without some symptom.  I guess the good news (I think) is that the pain is less, but what concerns me is that this is not stopping and now my legs are twitching when for the past several weeks only my hands and feet were affected.  My neurologist seems to think this is all because I stopped Seroquel suddenly.  In a sense, this is somewhat relieving, but at the same time, I have not been able to find any other reports of similar withdrawal symptoms online.  I did not have ANY of the common withdrawal symptoms.  My two main concerns are: 1.) Will this ever permanently stop, and 2.) What happens if it continues to progress?  Lastly, what else do I need to do to rule out the "big bad" diagnoses?  I am a very active and healthy 43-year old woman.  I take no other medications.  I tend to agree with the neurologists' theory as the symptoms coincided with the termination of Seroquel.  Aside from what I am experiencing now, the sickest I've ever been is when I had pneumonia.  Kinda freaking out!
