Hi @dlydailyhope

Many thanks, I would need to book an appointment with the doctor.

At least reading through Cervical radiculopathy, I don't seem to have much in that sense, e.g. (sensory), there is no numbness or reduced sensation in the skin, no motor weakness, no reflect losses. Doctors appointments here ... just a GP, no idea even how long it takes. Emergency medicine (A&E) can land one with a 7-hour wait!

What I have is twitching ... just the muscle twitching in the biceps – I wanted to really rule out the worst ALS.

Wondering: In ALS cases, let's say absolute initial, is the twitching throughout the day? Or sometimes only?

Is there an idea of "micro-twitching"? E.g. I can sometimes see visible movement in the bicep, other times, I feel a "tremor". Again, not through the whole day, like today, nothing until 18.00 ... the whole day, I went about my work – nothing.

Can it start with just one muscle only?
