My mother is 47 years old and is in good physical shape. She has been sick for over a year now without any diagnosis. She has seen many doctors and has had a ton of tests done. Now she is thankfully at a doctor that might be able to figure out what is wrong her though. Anyways I thought I'd tell her symptoms, in case anyone knows what might be wrong with her. She has fluctuating blood pressure. It will be really low at one time and then another time it is extremely high. When she walks or anything like that her oxygen level will decrease (she had a test done where she walked up and down steps to see if her oxygen level went down and it did. The doctor thought the machine wasn't working because it went down so far so he put it on himself and he found out the machine actually WAS working.) She also gets dizzy occasionally, but I'm guessing that happens when her oxygen level decreases and her blood pressure is low.
If anyone knows what this sounds like, please offer your suggestions. I have been looking on the internet to try and figure it out without any luck.
