Thanks so much for your reply, no i made it in Koeln, not so famous but okay.

However I don't know, my muscles are so week especially the right part of my body, is that normal in myotonia conginata.

As for example when i stand up after siting a long time, i only stand on my left leg as I can not hold on the right leg until it is okay.

please is that normal.

Many Thanks

Peter, are you sure it wasn't paramyotonia congenita? That is a different ion channel disorder and can cause more weakness. It could also explain why the mexiletine isn't affecting you much.

Myotonia congenita is usually fairly symmetrical, so if you did feel some weakness, it would probably be pretty equal on both sides. Were you ever in an accident that injured your back? That would be a more likely reason for you to have the weakness in one leg. Also lesions in your brain or spine from viral infections in the past can do that. If you haven't already done so, I would ask your neurologist to do an MRI to see if there are some herniated discs that might be causing the problem.
