Experiencing Abdominal Pain, Edema, Anemia, Sharp Hip Pain, Leg Pain. Reason For This?

I am experiencing lower right and left abdominal pain , edema , anemia , sharp pains through my hip, around to my lower back and down my legs. I have spurts where i am short of breath and my legs feel like sand bags. Recently tested and thyroid is slightly elevated. I also have a hyatal hernia and an ulcer and endometriosis, all of which are being treated by specialists. My biggest concern is that i cannot sit up for more than 30 minutes at a time then i feel like throwing up, i have an extreme headach, short of breath and pressure in my ear. I have had everything but my colon and liver checked within the last 3 months. Any suggestions as to what might be causing these symptoms that we have not looked at?
