hi - I get complicated migraines and sometimes the numbness and tingling persists for several days after the head pain subsides. Also, unlike classic migraines, the aura with a complicated migraine (usually visual disturbances) doesn't always stop when the actual head pain starts and can linger for the duration of the attack. It can also take a few days for speech to return to normal. Hope this info helps. Will keep you and your husband in my prayers.
How is your husband? It is good that stroke was ruled out and a diagnosis of complicated migraine was reached. I agree with the above post that complicated migraine, which commonly referred to attacks of prolonged aura symptoms, could last hours to days. During attacks, patients develop stroke-like symptoms with sensory and loss of strength of muscles. Have him see his neurologist regularly for proper management. Take care and regards.
