Fun fact ...
Had a Mylogram a couple of weeks ago. No- one said anything about turning the SCS off during the test but I though - better to be safe than sorry - so I turned it off. About an hour after I asked the nurse who was looking after me whether I could turn it on to help with pain relief and she said I could.
Now this is where the fun started ... Stimulation was very high up around my rib cage instead of being in my legs where it usually is. It also felt weird - sort of like it was distorted by being under water (strange description I know but this is what it made me think of at the time). Realised it was probably due to the extra volume of liquid in my spinal canal so I turned it off. Kept trying every hour or so until it started to work normally again (about 5 hours later)
Though I would share this because I think it could be dangerous to have the SCS on when they are injecting the dye in. Could cause unexpected stimulation and potential movement when they have the needle in.
Was particularly disturbed that no- one told me to turn it off prior to the Mylogram.
Keep on keeping on
