Suggest Treatment For Severe Migraine Headache

Hello. I ve had a migraine for over a week now. I ve been to urgent care about it and seen my primary care doctor about this. I ve been on MagSalt and another medication that s combined with tylenol and caffeine. During my visit with my primary care, I was also given an injection of toradol and that was on Friday. I woke up on Saturday with a dull but growing headache and it s gotten worse over the past two days. I ve been trying to avoid going to the emergency room, but my primary care has said that if it continued, to go to the ER. I ve only had migraines one other time in my life (as a teenager) and nothing since then. I have constant nausea even with the Phenergan and Zofran they prescribed. I barely eat anything, I do make sure to drink alot though. I also have SLE Lupus, Lupus Nephritis and MDS. I just need advice as to whether or not I should go to the ER tomorrow due to my symptoms.
