Im a 16 year old girl with Mitochondrial Disease/dysfunction and was hoping for an answer to my peculiar case. Everyday, I constantly deal with muscle fatigue and pain along with migraines.. but now a few new symptoms arose. They include high heart rate (130 resting), anxiety (currently being treated), and a sharp pain within the left arm pit. Weve visited the cardiologist (more than once) with multiple EKG, echocardiograms, and 24 hour halter monitors.. but every doctor is stumped. Now Ive come here hoping for an answer. Do you think any of you will be able to help?
Hello, Your clinical situation and past medical history, it is important performing further tests to investigate your heart. In this regard, I would recommend performing a cardiac MRI.  If this test results normal, you should consider anxiety as a possible cause underlying your complaints.  It is also necessary checking vitamin D, vitamin B12 and blood electrolytes, coupled with thyroid hormone levels. You should discuss with your doctor on the above tests.  Hope I have answered your query. Let me know if I can assist you further. Take care
