thanks for writing I feel sorry for you since its already 3 days I assume you have taken painkillers like aspirin or ibuprofen which proved to be ineffective I would recommend you following the combination of acetaminophen, aspirin, and caffeine (Excedrin Migraine)if you are having moderate pain you can also take sumatriptan (Imitrex) or sumatriptan and naproxen sodium (Treximet)for severe pain migergot is also helpful you will also need anti-nausea medicines metoclopramide (Reglan) or prochlorperazine (Compro) I would recommend you to stay home preferably in a dark place for few days. once you are alright you may need a prevention therapy, please let me know if you want to know more about this. I hope this was helpful and feel free to ask any related queries get well soon
