Most migraines are nothing to worry about and most migraines will go away on their own within 1 to 3 days even without any treatment.
However if the migraine lasts longer than a week or the migraine gets worse or comes back often then you should see a doctor about the migraine.
If you're just experiencing migraines wit would first be best to see your doctor or go to a walk in clinic and let them know that you're having migraines that are not going away or the migraines are lasting too long.
Sometimes migraines can indicate brain cancer or a brain tumor or something else going on in your head but the good news is that most migraines are usually caused by stress and other less serious things.
Taking some pain medicine such as Aspirin can help relieve most migraines.
I know when I'm stressed out such as dealing with my kids they give me a migraine that can last for a few days.
So being stressed out can cause migraines because you have higher blood pressure.
If the migraine lasts longer than a week or gets worse or they come back too often then go to the doctor or hospital to get checked out.
