I recently had flu like symptoms accompanied by a three day fever that hit 103. A day or so after I was feeling better I had went to see my doc for a follow on my shoulder. I mentioned that fever and he wanted to do some blood work to make sure everything was on the mend. Fast forward to today and I get a letter from him saying that Hemoglobin level was low (12.5, Im a 33y/o Male) and that he wants to do additional testing. Is it possible that the low level was caused by the bug/fever that I was recovering from?
Hi your have he level 12.5 which is slightly low only. It may né due to fever or may be due to some deficiency like iron or it b12. So just go for further investigation.  It's not a big or serious problems. Thanks for using Chat Doctor.
