Astrazenca Booster


I had the same with Astra Zeneca. But not with Pfizer.
Practicing good hygiene is essential for your health. Wash your penis and groin area often to keep it clean.
Poor hygiene can cause a build-up of smegma, an oily, malodorous, and irritating substance that is known to occur below the foreskin.
If smegma builds up, it can cause inflammation to the adjacent skin. This can be uncomfortable and can be a cause balanitis, a condition where the head of the penis becomes red and inflamed.
Even with a circumcised penis, less than ideal hygiene can lead to penile irritation and inflammation, including balanitis.
Headache is one of the possible side effects. Does not usually last long. Take couple of painkillers. I had mine at 10Am, was fine all day, woke up during night cold and shivering. Next day absolutely fine !!
