Hello i am 20 years old. From several days maybe 1 week i have dizziness, headaches and my right leg and hand became extremely weak. I can still; make push ups , i can walk and run but i feel them VERY weak. I went to MRI scan whjich was clear except a small cyst 9mm in the pinneal gland which the doctor told me that it is usually not a big deal and it shouldn't be treated. My question is could that weakness be some kind of early ALS symptom?
