Hello I've never posted here before but I remember not too long ago searching everywhere for answers. Because I finally got an answer that helped me, I'm trying to spread the word to help other people.
I was diagnosed with chronic fatigue syndrome after searching for answers for alomst 6 years. I was tired ALL the time, sleeping way too many hours a day. I would get lightheaded and I felt like couldn't think straight, like I had a foggy brain. I also had frequent head aches, muscle aches and blurred vision sometimes.
I was finally sent to a great doctor who changed the diagnosis from chronic fatigue to Neurally Mediated Hypotension. All of my blood tests came back normal, and my blood pressure was normal, until he took it while I was laying down. Then it was too low. Now I take a blood pressure medication (for me it helps to actually raise my blood pressure-instead of lowering it like we always here about) called Propranolol. I feel sooo much better with this medication.
I'm not saying this is going to help everyone, but if you have the same symptoms as I did it can't hurt to get it checked out. They can also do a tilt-table test to diagnosis for Neurally Mediated Hypotension.
Good luck!
