Since one year I have persistent low grade fever between 98.8- 99.4 f. It stays for few days then goes away. Then it happens suddenly then goes. I have got a cbc done recently. I am having low haemoglobin, mcv and mch. Haemoglobin is 11.70, mcv - 71.30,mch - 22. 50. Rbc count is 5.18 and rdw is 16.90. Lymphocytes are 40.50. Last year also the levels were almost same. Should I start any medication? What does it mean? Is there something serious. Please advise. Rn also i'm having 99.2 f.
