Hi, I got my blood work done as I am facing post covid complications like fast heartbeat, dizziness, ringing in ears, intermittent low grade fever, restless leg syndrome from past 5-6 months. I am 29 years old and was absolutely healthy before covid. My
ferritin is just 5 and the ideal range is 11-306 ng/ml. It is surprising my
B12 is 500 pg/ml, folate is 17 ng/ml, iron is 70 haemoglobin is 11 (All other tests are also nearly normal like
CRP, ESR). My NTPro BNP is raised 160. What could be the reason behind this because only ferritin is low and other tests seem normal? Are my debilitating symptoms related to that? Please advise and help me. Thank you!
