I can't believe some of the misinformation you have been receiving regarding chiropractic. I am a chiropractor, and we are spinal specialists, perfectly capable of dealing with a case such as yours.
The last person went so far as to suggest your chiropractor is more concerned about your money than your health and I'm assuming they have never met. (A prejudiced statement)
I am going to give you an independent, second opinion, based on my expertise in the field.
Your chiropractor has a multitude of possible tests he may have performed to give him input into whether your issue is a disc herniation, muscular, or subluxation based; including Dejerine's triad, SOTO Hall, Valsalva's, muscle testing, reflexes, dermatome sensation testing, palpation, etc. I am assuming that he has performed some of these tests and developed a diagnosis and care plan for you as an individual. He probably has spent the most time with you and has the best clinical indication of what is taking place out of any input you are receiving from any of us.
There are only three contraindications to receiving chiropractic care; if the area that needs to be adjusted has cancer, a fracture, or osteomyelitis (infection). Everyone else is a candidate for chiropractic care and can benefit from it. Disc herniation is a regular case I see in the office and can be treated safely and patients show great improvement. Many have avoided surgical intervention, which should be a last resort. There are many different ways to administer an adjustment or manipulation and if you have a good chiropractor, he has many different forms he can utilize which range from higher to lower force or gentle adjustments.
The most important person to be listening to is YOU, your body. If an adjustment doesn't feel right then mention it to your chiropractor and he can modify his delivery so that you are comfortable. If they don't have different techniques you may need to look for someone else.
There are 2 reasons you don't need to have an MRI right NOW:
1. Your chiropractor is following the standard of care. This very well could simply be vertebral misalignment and muscular issues (the 99.9% according to your chiropractor). Treatment and monitoring for improvement is the right thing to do. If in two weeks you are not responding to treatment, standard of care is to change the treatment method (rehab methods for example) and monitor for another 2 weeks. If again no improvement, then I would consider having the MRI.
2. MRIs are expensive and should only be used when clinically necessary, i.e. when a diagnosis, treatment, or prognosis cannot be given without the information that would be gathered from the MRI. Many disc herniations can be diagnosed without an MRI, in some cases MRIs are necessary but not all. Time will tell. Regardless of whether insurance, your government or you pay for an MRI out of pocket, YOU pay in the end. Healthcare systems across the world are crashing because of the expense of employing advanced technologies such as MRIs. If done too soon and the film comes back clear, then that money would have been better spent training staff, increasing nurse and physician staffing, or buying equipment. When necessary a MRI should definitely be done, but only when necessary.
The last thing I don’t understand is if the ER was so sure you needed the MRI NOW, why didn’t they take the time to order one for you right then and there?
Sorry for the novel, but I truly wanted to help you. I hope you have a speedy recovery.
