Recurrent stomach aches, dizziness, have head wooshes, am nauseous, anemic and urge to pee

Hi. I'm a 19 yr old female. I've recently gotten pretty sick to the point where it's been ruining my quality of life. Anyways, here it goes... I've started getting these stomach aches that come on very randomly.. the best way to explain it is if all my organs contracted at the same time and pushed together and then pushed back out. I have never had pain like it. It's not helped with going to the bathroom or anything and isn't followed by an urge to have a BM. Anyways, I've been tested for many things and have had my colon and stomach scoped (inflammation in colon but no chrons or colitis and clean sotmach but a small hiatial hernia). The doctor said that there is swelling so somethings happening, we jsut don't know what. I also recently became anemic.. they don't know where thats from either but it is iron deficiency. I eat a ton of meat (red and white). I started taking iron pills which have defeinitely helped me feel less lightheaded, but now I'm getting dizzy again.. I'll be walking and then hear a woosh sound and I get kind of cloudy and feel as if I'm kind of shutting down... then I start twitching. Also, I have shingles. I know something is going on and it's not in my head because you can't cause shingles yourself and anemia. I'd just love a jumping point to talk to doctors about because I feel like I'm getting nowhere and doctors think I'm crazy or something.. It's scary when the dizziness happens. I also get very nauseous when I'm hungry, have lost about 10-15 pounds, have been eating a lot and recently (the past 2 days) have been having an urge to urinate... 2 days ago it was bad, yesterday it was back to normal and then back to bad today. Two days ago my dizziness was also at a new high. I've had some pressure with that urge (oh and nothing really comes out). Let me know what you think.. here are some other facts.

- Clear CT Scan of Abdomen and Pelvis - But a cloudy spot in my lung from a recent episode of pneumonia
- CT of Brain/Neck showed cyst in a maxillary sinus

Let me know if anyone has anything similar to this or any idea of what's going on... Thanks for your help.
