<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 36 yo female who is 6 weeks pregnant. I have been having muscle fasiculations in arms and legs for about 2 months off and on. more regular now. They happen when my muscles are at rest. Also get tremors in hands after exertion or holding heavy cup, cell phone etc. Worried I have ALS. Going to neurologist in two days but totally panicked  <response>: ALS can happen to anyone, but it is only one disease in a larger family of diseases called motor neuron diseases. Rhat being said the whole family of disease is rare and articulations are often misdiagnosed and even when correctly diagnosed are only a symptom of a peripheral nerve injury which has many forms and locations. There is no way online whether you have ALS, but your neurologist will sort it out
