Thanks Dr Corenman.
Have had further review by immunologist to no answers.
Back at the original neurologist today and after discussions he is now suspicious of electricial issues causing my symptoms and raised protein. Has scheduled me for an EEG and prescribed Epilim to trial after the EEG.
Has also ordered T3 MRI imaging of brain and c-spine again to give up any other clue. He advises T3 imaging can show more around blood vessels that could be bleeding to try help explain raised protein.
The discs bulges are still at the end of the list. The new information I received today makes good sense, hopefully this might be the right track!
