I'm a bit confused by your post.
You had 6 epidurals in the past year, which is quite a bit during a one year period. Usually epidurals are given in a series of 3 injections over a few months. not 6 of them during a 12 month period.
Are you saying that your June 26th, 2009 problem is with your PM doctor or is that when you herniated disc problem began?
Are you stating that you are using a cane or walker to get around and your doctor won't give you one?
OR
are you saying that your doctor won't give you narcotic pain medications?
You post on this is very confusing.
As for your questions about narcotic pain meds.
Pain doctors don't like patients to tell them what pain meds they want. That puts up a red flag to them that the patient may or may not be abusing the narcotics.
Pain doctors walk a fine line in providing narcotic prescriptions and do need to be careful.
Since the death of Michael Jackson 6 weeks ago, their is some panic amongst pain management doctors and prescribing. They are being carefully monitored as well.
Have you signed a pain contract with this doctor?
It may be that you will need to find a new pain management doctor, but telling one what narcotic pain meds you want is not a good idea to do.
As for a safe amount of narcotic that one can take, well that is really an individual situation with each patient.
You can build up a tolerance to the pain meds and then need higher and higher doses for it to be affective for you.
It is hard to get off pain meds and you do need to slowly wean down over a period of time. How long and how difficult it can be, also depends on what narcotics you are taking, what the dose is, and how long you are taking them.
Now, if you have really had 6 epidural injections over a period of 1 year, and you are still in this much pain, and you have done PT and decompression (which usually dosn't help, but can really make you disc worse), then it does sound like you only option for pain relief is surgery.
What kind of surgery is your doctor talking about? What is the doctor planning to do?
Has your PM doctor talked about using a nerve pain medication, neurontin or lyrica to help ease your nerve pain? Narcotics are not very affective at relieving nerve pain. This may help your pain levels.
Spine surgery is a huge decision, on the other hand, the right surgery for the right situation on the right patient, can be very effective in relieving pain and returning to a normal function again.
Have you had more than one opinion on surgery? That is also another very important thing to do before making that surgery decision.
If you give a more clear post of information and answer the above questions, there may be more information that I can provide for you or explain further.
Good luck
