Definately agree about the vertigo, its the pits! as for the large area affected, a few weeks ago i went to bed with pins and needles in my left hand and arm, in the morning i woke with my left arm and shoulder feeling as though i slept akwardly and it had gone to sleep. It did improve a bit over the next few hours in that i could move it but it felt very heavy, but i still had decreased senation to most of my hand and arm. Now, it still feels heavy at the shoulder, my hand varies from pins and needles to numbness and lack of strength particularly my thumb, index finger and middle finger- it gets worse as i am tired, i am still recovering from a series of flares so i am hoping that things improve a bit but i am still getting new minor symptoms, eg the left side of my face went tingly the other day and then gradually went numb like i have been given a shot of lidocaine- it has eased back a bit but is still decreased sensation. As for the size of the area that is affected, it seems to be like evrything else with this disease, it seems that it varies from person to person, i know of someone who had the just about the whole right side affected as if they had had a stroke and i know i have had some small areas like a small area on my foot- just depends where those plaques form i guess
