My sister is 14 years old. This recent summer, she started feeling nauseous. After some testing, it was discovered that she had a parasite called giardia. After being treated for that, her symptoms got worse instead of better. She was (and still is) experiencing extreme fatigue, dizziness, and an irregularly fast heartbeat. After further testing, she was diagnosed with POTS (the autonomic nervous system disfunction) low potassium and enlarged red blood cells. Recently, the area behind her right knee became inflamed and is hard to the touch. Nothing showed up in the x-ray. So all together, her symptoms include extreme fatigue, the symptoms of POTS, and enlarged red blood cells. She is weak and sore and her bones hurt. She is also shaky. Is there any connection that be made between these symptoms? Also would a full body MRI be beneficial?
She has already had a thyroid test, a b12 test, all gastro tests, anemia test, hypoglycemia test, and Addison's disease test.
I am sorry to hear about your sister’s medical problems. She appears to have had many investigations. Foliate should be measured if B12 is normal. This can also cause large red blood cells. Liver diseases including hepatitis should be investigated. Also, conditions such as leukemia, IBS, kidney diseases including glomerulonephritis should be tested for. Please discuss with her treating doctors. Take care!
