Hello and welcome to EmpowHer,
There are many possible causes for migraines which can include but are not limited to:

--eye strain -- sometimes a person can need glass or have a wrong prescription for their eyes causing eye strain.

--back problems -- Though it may not be the only cause, it can be a contributing factor

-- allergies -- there is a possibility of having unknown allergies perhaps to food, animals, or plants. Common food culprits include: chocolate, caffeine, alcohol, and dairy.

-- hormonal imbalances -- premenstrual migraines usually happen right before your period when the estrogen levels drop. However if you have irregular hormonal imbalances caused by a thyroid problem, IUD etc the migraines could be at any time, not just before your period.

--Other contributing factors: concussions or stress/anxiety.
I suggest that you speak with your doctor about your migraines, especially if you have a fever coupled with them.
