For Nearly 3 Weeks Ive Been Experiencing Horrible Headaches That

For nearly 3 weeks Ive been experiencing horrible headaches that are localized on the left side and makes my eye on that side water/swell/redden. they have progressively gotten worse and ive tried everything over the counter but nothing works. the only things that give me barepy noticeable relief is submerging my head in hot water or lots of coffee but the very little relief it gives me doesnt last long. when the headaches arent there they come back as soon as i stand up pounding like a pulse and i have to walk softly or its unbareable. ever since this has started ive also had pain on my inner right hip right inside the hip bone. i have had a csection in 2013, gallbladder removale in 2013, take no medications before this, had an ovarian cyst burst in 2012 and have an iud for birthcontrol. ive been trying aleve for relief.
