Hello. I am a 36 year old female. I have been experiencing twitching in my right bicep for about a month and a half. It will come for about a week and then go away for about a week. The twitching does not prevent me from any activity but I can see my arm twitching and sometimes it feels like popcorn popping in my are.

I do not seem to have any other symptoms. I have a co-worker who has ALS and his first symptom was twitching in his shoulder. I am trying not to worry but I can't seem to stop worrying about it especially when I keep getting reminders from the constant jumping under my sleeve!

I am going to see a neurologist next week but if you can give my any advice to think about before then, I would appreciate it.
