Hi popeye. I am sorry to hear of your problem as I can identify only too well with this. In the uk, consultants will delay patient investigations for years to save money.
Like you I have had the same situation in trying to get further tests done -i had some mri which are showing a "mild" prolapse at l5/s1, I am told this is not particularly diagnostic for my symptoms of back pain, numbness in the legs sometimes and muscle spasms.
I have also seen a neurologist and a neurophysiologist, had emg, bone scan, lumbar puncture and countless other tests, there is evidence of minor neurological deficit yet I am being told "you have not reached the threshold at which the pain clinic can do anything for you". What threshold are we expected to reach?
Already I am living on morphine tablets and liquid, this has been going on for three years now and I am getting worse and worse with the neuro problems, muscle stiffness, bladder problems, pain in low back dropping into left buttock etc.
I was mistakenly diagnosed with multiple sclerosis, upon my own independent uptake of a second opinion, this diagnosis was rescinded. I have reached a stage where I have no confidence or belief in most doctors I meet. There is one doctor who is fully engaged into helping me and has tried numerous things, botox, epidurals etc, he is the only doctor whom has not given up on me and is still trying to elucidate matters to final conclusive diagnosis. My next step is also a neurosurgeon whom is experienced in pain management.
What I can advise is that I have achieved very powerful results when I have invoked my mp's support when the hospital get sticky about doing further tests and putting me on long waiting lists. I have been quoted mri waiting times of 18 months and my mp got me them within six weeks. 18 months for a diagnostic test is simply not acceptable.
I agree that you must insist upon a referral to a neurosurgeon - realistically the decision of whether or not surgery is a necessary intervention lies in the hands of the person whom has experience of carrying out this surgery. Do not be fobbed off - if you become increasingly disabled now, it's too late after that!
I would imagine at some stage depending on the outcome of the neurosurgical appointment that you should potentially consider seeing a solicitor regarding clinical negligence, it sounds like you are in an extremely similar position to me overall but mismanagement of chronic pain is unacceptable. Allowing neurological deficit to worsen if it is cause by orthopaedic correctable problem is negligent medical practice.
Popeye - basically we're pretty much in the same place here albeit minor differences in symptoms, if you wanna chat then drop me an email, regards annemarie
