I had a baby 4 months ago and have been getting headaches and migranes almost everyday for the past few months. what could be causing them?

Need more Info: What was the timing of the headaches onset-how soon after delivery.Did you have heavy bleeding or prolonged hard labor, or an epidural ?Have you had any visual chages or problems nursing?There are a number of possibilties for your headaches. You need to see a neurologist. Possible causes are post-spinal headache or low pressure CSF headache which can occur even without having a epidural or spinal.

Anything: Your headaches could be coming from tension, dehydration, lack of sleep/poor sleep, skipping meals, stress, eye strain, teeth grinding, sleep apnea/snoring, or chronic sinus problems.
