I'm sorry for what happened to you. I'm not sure I understand about taking/or refilling your prescriptions too early. Do you mean that you ran out of meds too early? If so that is unfortunate. I've never run out of meds too early but if I hadn't an understanding pain doctor who increased my meds when my pain increased, I could have ended up in the same situation.
I have a degree in Health Information Management/Medical Record Administration. The law says that you are entitled to a copy of your medical record. Many offices will tell you that they will only send a copy of your records to another physician but if you tell them you know the law and your rights, they will probably make a copy of the records for you and not charge a fee.
I had trouble with a physician once because he threatened to discharge me from care because he wanted me to do couple's counseling with my husband included and we couldn't afford it so he told me he had to discharge me from care.
They were willing to send my records to another physician, they will do usually do that if you ask them to. I didn't have a doctor yet.
I went to another pain management doctor with records that I had from other physicians offices and told him that I left the care of the other physician due to insurance problems.
I had enough other records that he didn't seem to be concerned about the records from the doctor I had just seen.
I agree in principal that you should always be honest with your next doctor about what happened with your other doctor but you need to realize that doctors are very skittish about taking patients who have had any problems with a prior physician.
This is because of new governmental regulations and the past practice of DEA raiding a small number of doctor's offices. They only ended up taking a few doctors to court but it was enough to scare many doctors.
I am not trying to spread tales. If you want to know more about it then you can find information by googling it.
Also, the FDA is coming out with stricter guidelines for prescribing narcotics.
What I would do in your situation (this is only my personal opinion) is sign a release and request that your former doctor's office give copies of records to you personally.
Then I would go through the records and see actually what the doctor has written. Often times, if the doctor knows that your records are going to you, they will leave out any "controversial" matters that occurred because they are worried about liability issues.
If this happens then you will not need to discuss the matter with the other doctor and you can tell the new doctor it was your decision to leave the doctor's care because of miscommunication with the office staff or something like that.
Even if there is something about the incident in the records, you will be better prepared to discuss it with the doctor.
If possible, it is better to bring the records with you so that you are there to discuss the incident with the doctor.
I wish you the best of luck.
