I am currently 24yrs. old with a ton of symptoms. Can someone please help me. I was diagnosed with autonomic dysfunction back last year but, my symptoms are still here and as of a few months ago I started swelling in my feet almost to where I would have pitting edema. I am not a diabetic and am very petite so this is VERY strange for me. Ive seen numerous doctors and am currently seeing a doctor who is trying to run every test possible on me so hopefully, she or someone on here can help me or give me ideas to mention to her. Here are a list of my symptoms: -Extreme fatigue every day I have no energy and I sleep all the time. -Swelling in my feet and ankles usually comes with extreme weakness and pains. -Headaches/Migraines -Frequent Urination -Blurred vision -Fainting/Passing out with rapid heartbeats, my heart rate has been up to 213bpm! -Waking up with rapid heartbeats while burning up as if im running fever PLEASE HELP!
