Do not use illicit drugs. I'm not talking about medical Joint Pain Hack Review marijuana, although that may be a factor in whether or not you would be accepted by a new pain doctor (and also maybe why you got fired in the first place). I'm talking about heroin, cocaine, ecstasy, etc. Understand? Your new pain doctor will be drug testing you as is the norm these days. It would be a waste of your time and the doctor to pop positive for one of these substances on the first visit. If you have insurance, use it. One of the distrust factors in pain patients comes in when they use insurance for one doctor and cash for another. It is a red flag and is one of the top drug seeking behaviors.
Be flexible in your pain medication needs. What I mean by this is when you see your new doctor, do not be overly insistent on a specific medication at a specific dose. This can be another red flag for drug seeking behavior. If you are seeing a board certified, fellowship trained pain management doctor, do you really want to question too much the wisdom of that doctor's experience? The last and most important tip is to simply be very very nice and respectful at all times of the doctor and staff.
Pain management patients can be very difficult to work with due to the complexities of the individual's condition. Making things complex for the doctor is one thing, that's typically what he or she likes is mental stimulation and helping people. Being downright rude will ruin the trust and relationship from developing. You will get fired again, and that includes being mean and disrespectful of the office staff.
