migraines, severe headaches and infections

Hello!
I haven't had a whole lot of success with the dr.s I've been to so I thought I'd see if anyone here has any ideas. I don't know which category I fit in so I posted in a couple different ones. Any input is greatly appreciated. The below is the short version, honest!

When I was very young I had frequent bladder infections & kidney infections which damaged my left kidney. Other than that growing up I was healthy & happy w/ plenty of energy. When I was 17 I started falling asleep very early every night (7-8pm) and had constant bladder pain & pain w/urination. Tests would come back w/ presence of white blood cells & traces of blood but no infection. Hypersensitive bladder, said one urologist. Then I started having pain in my stomach & upper sides, which dr. thinks could be colon. They determined I have gastritis, acid reflux & esophogitis and prob. an IBD. The bladder & side pain is worst before, during and after periods plus I have very long, heavy & painful periods so drs. suspect endometriosis. Things have escalated since June 07 when I started getting migraines & severe headaches 1-4 times/month that would last anywhere between a day - 2 weeks. The headache types vary - classic migraines; all-over splitting that gets worse if I move; stabbing w/sensation like nerves or blood vessels in head are on fire; etc. I've also been catching a lot of viruses (5 times in 5 months) & infections and even when i'm not "sick" I still have chills, achiness, nausea, fatigue, weakness & swollen glands in throat & neck. I also get that sensation when you eat something tart or acidic where ur saliva(?) glands go Zing!! except for me it happens randomly and lasts for hours/days. In the past couple months I started having these sweating spells in the middle of the night. I'm not hot, I just start pouring sweat. It's weird because I'm almost always cold & I rarely sweat. I also get low-grade fevers when I'm especially not feeling well and I've developed a non-itchy rash that started as a small patch between my breasts & has spread out & up my neck & shoulders. The rash flares up - gets redder & spreads - when I'm feeling especially crummy. I'm thinking some of the above could be hormone related, even though I've been on the "mini pill" for 4 1/2 months, because my periods have been weirder than normal as well. They used to be every 4-5 weeks for 7-10 days and very heavy, as I said b4. But in early Dec. I had a period after only 3 weeks, then the next one came 5 weeks later, then 2 1/2 wks later I had a lot of pain but bled only a tiny bit for a few days, then a week & 1/2 later I again had more intense pain in the lower region but I only spotted a couple times.

The doctors I've been to have for the most part just tried to figure out and fix isolated symptoms but haven't looked at why a previously healthy 21-yr old girl would be having so many health probs. I think they get a little overwhelmed by how many symptoms I have. I'm hoping someone who reads this post might have an idea of what could be causing all this, or could recommend a type of doctor/specialist to see. Dr. House's cell # would be great, too
