When you donate blood, the nurse takes a sample of your blood and checks to make sure your iron levels are high enough and also checks that the blood pressure is not high.
If the level of iron is not up and the blood pressure is high, they will not take a donation of blood.
After giving a blood donation, some people do feel a little queezy, but whenever I have been, we get a drink, tea, coffee or juice and biscuits.
It takes 3 months for the blood iron levels to build back again. In my case it was double that.
People do not get flu symptoms from donating blood.
What kind of flu symptoms are you experiencing? May I offer a suggestion? Please report these symptoms to the place where you donated the blood.
I know headache can be a symptom of many things, but one of them can be iron deficiency anemia. Were your iron levels on the lower end of normal prior to donating?
After donating blood you need to increase your water, fresh vegetables, meat/kidney beans/chick peas intake several fold.
Take pain relief as recommended on the packet to lower your fever.
Rest in bed and drink plenty of warm juices.
You can do steam inhalations and also apply Vick to your chest if you feel congested.
There is not much else you can do for an influenza virus. Antibiotics have no affect on virus infections.
If your symptoms don't start to ease in a few days and start to get worse, then contact your doctor to make sure you do not have a secondary bacterial infection.
It is nice that you can give blood. They won't take any off me anymore because I suffer from hypertension now.
Donating blood will not give your the virus. You must have been in contact with someone who was contagious.
Wishing you a speedy recovery.
