Verpamail discontinuation PAIN!!!!

I was recently prescribed Verapamil [after several other medications failed] for my "migraines" that I have on a daily basis. Migraine is such a vague word to describe the pain I am in.... I consider it more of brain zaps, a tingling burning pain that happens everyday. [If you have read my posts before I know is seems that I am repeating myself but I really need help]. Monday I was rushed to the hospital bc I had terrible chest pains and shortness of breath, the Dr. who prescribed me the Verapamil says that it could of been caused from a "reflux" of the medication, and told me to abruptly stop taking it and that weaning myself off wouldn't be necessary, granted I have only been on the medication for a couple of wks but I have always been told you must wean yourself off of any medication b/c abruptly discontinuing something could cause major problems. It has been two days since I've had a pill and my head is in extreme amounts of pain... could this be directly related? Please please please give me any suggestions you may have. Thanks in advance!!!
