Having Severe Head Ache. Diagnosed With Migraine. Other Conditions Are Sarcoidosis Of The Lungs, And Narcolepsy. Treatment?

My husband has not been headache free for more than 12 hours at a time for two weeks. This is a sudden occurrence as he hasn't had headaches before. Prior to this beginning three months ago, he was treated for pneumonia twice with antibiotics and steroids he was on the last of his taper dose when the headache with congestion suddenly hit in the middle of the day within a couple hours. The headaches came on suddenly and severe. He also has a droopy right eyelid, and metallic taste that is bad enough that he is not eating much. He went to the er on the 4th day and after normal ct scan and xray was diagnosed with migraine, given a shot and sent home. He was in more pain through the night and next morning. After home dose of my migraine medication, foricet, the headache was gone. He also has had high blood pressure ( is normal is a low normal reading). After a second visit to an er ( this one a large university hospital) his pressure was 180/140 the dr dismissed the reading as white coat syndrome ( has never happened to him before). Dr there diagnosed a cold! He takes readings at home now and are consistently high with a unusual for him higher pulse rate 90+ . The headaches are so severe he cries. He is taking 1/2 or 1 tablet of leftover codeine pain medication which usually stops the pain for a while. He is really foggy today, answering no knowing what he said when answering questions, ect... His other conditions are sarcoidosis of the lungs, and narcolepsy. What next? a cardiologist or neurologist? MRI with contrast? MRA?
