I am in a POIS state for almost 3 months. And that without any sexual activity. First I thought it was candida, then a histamine problem. Today I got the result of a new blood test. Conclusion: my iron is too low. My symptoms are the same as my POIS-symptoms:
Feeling cold
White tongue
Dry skin (but oily nose and forehead)
Itching after taking a shower
Cracks in my lips
Acne
Insomnia
Feeling weak
Feeling tired
Brain fog
Now I have to take 40 mg of iron every day. Because the sympoms are similair to my POIS-symptoms I asked my doctor if it is an idea to take the iron an hour before sexual activity and if could be helpfull against POIS. He said that it is possible. (I am not encouraging you to try it. Always ask your doctor first). So I will try it about a few weeks.
I am not a doctor. But my new personal theory is that POIS causes a shortage of red and/or white blood cells and platelets (trombocytes). Iron plays a role in this. I am not onky sick because of too low iron. But also because there is 1 similair side effect of 3 types of antibiotics, Paracetamol and Fluconazol: a shortage of red and/or white bloods cells and platelets. When you google what the symptoms are of this you will see a lot of POIS-like symptoms.
I had my last pill of Fluconazol yesterday. And I stopped with antibiotics and month ago. And I also do not use Paracetamol anymore. Today started with taking iron. When I get better about a week or two weeks then I know that my problem was that blood cell shortage and/or iron defiency.
