Question: Unexplained fainting, weight loss, stiff muscles

What is wrong with me?

Symptoms began: 9 months ago

Symptoms detail:
I have passed out 8 times since November of last year. I also have had an unexplained weight loss of 20lbs. I was in the hospital for 2 nights this week, they did an ECHO a stress test, an electrolyte workup, and a urinary analysis. I have also had an MRI, countless EKGs, an EEG, and had a ZIO patch. All have come back negative. I have seen a neurologist and a cardiologist. I have continued working with my therapist but she doesn’t think that these are related to psychological problems. It’s frustrating because this has significantly impacted my functioning as I lost a scholarship and can’t attend school without it.

Directly after the stress test I fainted. They were able to get my blood pressure which was normal and my heart rate, a bit accelerated but returning to normal. It was rather easy for me to get my pulse up to 199. I feel like it’s almost TOO easy to get my heart rate to accelerate… when I stand up my pulse will race to 120-130. The nurse made a note that I had stiff muscles during the faint which lasted 4 minutes. This time, when I passed out I was aware of everything happening around me but was too weak/unable to respond. I had a headache directly after coming too, which was sensitive to sound and light.

On Monday I passed out twice and felt VERY fatigued. Upon regaining consciousness the second time I felt as if an elephant was sitting in the middle of my chest, 7/10 and taking deep breaths exacerbated the problem . I typically feel a bit disorientated and as if the room is spinning but not in any pain after I pass out. My left leg felt tingly and 10ish minutes after passing out as the paramedics evaluated me my left shoulder felt like I had pulled it, and was in pain 8.75/10. The chest pain dulled out and was no longer noticeable 10 hours later when I was admitted to the hospital. also upon arousing my vision remained cloudy and dark, as well as being sensitive to light.

The night after I pass out I typically experience lower back pain and pain in the right side of the neck, but this might be related to the stress of fainting.

Personal medical history:
I was born with congenital hypotonia. I am diagnosed with Aspergers syndrome. I also have hypothyroidism. This was my first time being hospitalized.
I had a turbinate reduction surgery in may 2016. And when i was little ear tubes were placed in 2000.
i have an allergy to latex and had a bad reaction to steroids.

Family medical history:
My family is relatively healthy with 2 of my great-grandmothers living past 90, all of my grandparents and their siblings are still living. my grandfather has some heart problems but I am unaware of what it is exactly. no sudden or cardiac related deaths.

Personal lifestyle:
I used to be a student at the University of Portland but lost my scholarship due to this illness. I had attended a very prestigious and rigorous high school and never had any problems, even while taking classes for college credit (VIA. the AP program). I never smoked or drank alcohol. There is absolutely no chance that I am pregnant as I abstain from sex. I am as innocent as they come with no bad habits. I exercise regularly on the treadmill walking a mile every day for 15 minutes and walk all over campus, but would definitely not call myself athletic. I eat a normal diet, though will not be the first to admit that I could eat better, with the occasional doughnut, ice cream and cupcake thrown in.

Diagnostic or imaging test abnormalities:
Innumerable tests have been performed without any abnormalities being found. Had countless EKGs without any abnormalities, standard blood and urine workup with nothing, every time I went to the ER (7 times now). Wore a Zio patch for 2 weeks and did not experience an episode during that time. Have had an ECHO and stress test done, with nothing abnormal being found (aside from fainting directly after the stress test was performed). Had an EEG done and 2 MRIs one with contrast for the blood vessels.​

Secondary or partial diagnoses:
palpitations

syncope

Personal struggle:
I have lost my scholarship because I went to the ER every week for 3 weeks. I can’t attend my school without it and until I feel confident in a solution to the problem, I don’t feel like I can productively return to my studies. Without my return to school insight, I have lost numerous friendships and my first boyfriend. I used to be a strong believer in God but with all that is happening I truly​ doubt that he would do this to someone who has been nothing but faithful to him.
