After all stresses and strains of dealing with multiple symptoms, not having an awful lot of luck with my GP, and spending hours & hours on the internet ‘researching’, I have finally reached the most-needed ‘break-thru’ with a diagnosis. It’s still not completely diagnosed, but on a scale of 1-10, I’d say I am at 9.5! 
Just had confirmation on new lesions on my spinal cord, and new lesions on the brain, which weren’t there the first time around.
All meet the McDonald criteria - I feel a pig in poo! (very happy)
