Why am i having headaches like this?

Okay so i am 20 years old. I was diagnosed with PCOS(polycystic ovary syndrome) when i was about 15. Im not sure if this has anything to do with it, just getting the facts out there. A few months ago i started having headaches everyday. Some would go away with pain reliever and some would just stay there and just be a dull pain in my head all day. I also kind of feel tingly in the back of my legs and arms when i have these headaches, like im in a dream or aomething. About two weeks ago these headaches got so bad i was waking up with them and not being able to do anything with my day but complain. No pain reliever would soothe the paint. I went to one of my local hospitals and they told me it wasnt an emergency and for them to treat i needed to pay some money upfront(i dont have health insurance). So i go home and the back pain starts just in the middle of my back like i had been sitting up to long. Then i started my menstrual veey heavily (i only have about two regulars ones a year) a couple days later my head and neck hurts so bad im in tears and i have a burning pain all the way down my back. I went to another local hospital and they gave me a perscription for fiorciet and told me to follow up with a doctor. I have been sleeping for 3 days at a time cause the pain in so bad. Now i have pain in my eyes when i move them around or my head. I ahd a pulsing headache where i couldnt move my head, i was throwing up, back pain when i walk, neck discomfort and i am going off my menstrual today. Does anyone have any ideas? Help.
