Hello, I can t seem to find the answer to this question. My husband is 66, in excellent health, on no medications. He woke up and couldn t life his right arm past his elbow height. He couldn t comb hair/ brush teeth etc. Arm very, very weak. No pain. Have had MRI, it shows labrum tear in shoulder and severe stenosis in C3-7. Neurologist says he needs neck surgery, so does orthopedic surgeon. We are still waiting neurosurgeon appt. for opinion. No one thinks he had a stroke, as he has no other symptoms. We still think it is odd he has ZERO PAIN, and even though MRI shows defecits, why did this come on so SUDDENLY? Is it POSSIBLE, it COULD have been a stroke? And if so, how would they determine this? Would they need an MRI of brain? Should we get a second neuro opinion? Thank you. Sorry so long.
