Another pain..literally

I got dizzy back in April. It came in spells and was pretty bad, bad enough that I had to catch myself from falling sometimes. So I went to the Ear, nose and throat doc. Everything perfect and I wasn't dizzy anymore by the end of it all. Now I am again, not nearly as bad but annoyingly so. I have an MRI schdeuled for 10/13 if I'm not pregnant. Meanwhile I've developed lower abdominal pain, I WebMD'd it and it could be endometriosis. Hmm. I'll probably call the doc on Monday...argh.
