Muscle weakness and nausea
 

I get sudden bouts of strong nausea whilst using neck muscles if bending over and doing an activity for an extended period of time. The nausea and muscle weakness will go away with some minutes of rest. I know it´s not normal but don´t know if it´s myasthenically related.

Does anyone else have anything like this?

Anacrusis

(I am really looking forward to soon finally having a neurologist :) - after 5 years of fluctuating progressive symptoms :rolleyes:)

Sounds almost as if you have motion sickness. I know when my neck is weak I will wobble around when trying to do a task as you describe. That could definitely contribute to nausea!

Really? I have to admit my muscles aren´t that weak - but what used to be a thick strong neck muscle now feels like some spindly thread ready to snap on exertion - hence bouts of nausea. Motion sickness I´ve definitely had whilst reading a computer screen and wondered if I should start using travel sickness pills before logging on!
But it´s just like everything else that fluctuates - Each time you think it´s going to be the last and final fluctuation!

I also vote for motion sickness. I was feeling like my head was spinning and I was dizzy feeling. It was only when I was a bit weak and tired. Somebody on this forum mentioned that it might be due to neck muscle weakness. I started paying attention and I realized that the reason that I feel like my head is spinning is because it really is all wobbly. I had not noticed. If you can feel like your head is spinning from weak neck muscles, you can also have motion sickness.
