I know you posted this about a month ago. Was the MRI you had years ago done with contrast? It is important to one with and without contrast. I'm not sure what your GP meant by "ditzels". I agree with the others that getting your MRI report is important. Start keeping a medical record file as well as a symptom journal.
Unfortunately, autoimmune diseases can be difficult to diagnose, MS included. Being persistent is important in getting a diagnosis. If the chiropractor's adjustment helped for a bit, it may be worthwhile to continue that. Discuss it with your GP and the chiropractor first though.
I hope by now you are doing better. Please keep us posted on how you are doing.
