My Wife Has Had Two Episodes Over The Past 30

My wife has had two episodes over the past 30 days, both starting with a severe headache on the left side of her head, behind her left eye and in the bridge of her nose. Went to the ER for both. Each time she was given pain meds. CT scan and MRIs were done and clear, after the first. She was discharged after a few hours both times. The first time, within 24 hours she experienced numbness on the left side of her face that lasted for 5 days. The second time, she had numbness on the left side of her neck, torso and left leg. She was unable to walk without assistance for a few days. It has been 12 days and the numbness has improved significantly but is still there. She has had tremors for a few minutes, on two occasions after this second episode. She has pretty constant neck pain.
