Thanks for your reply.
Yes, the pic was from a reference.
I don't use Antibiotics since ages (I am almost never sick).

The only symptom I have is bloating and it is not severe. I started being bloated in October 2016, then in December (when the bloating was severe) I went to my doctor. He did a ultrasound exam and saw just air. I did the "ELISA" intolerance test and resulted positive to milk / yogurt / cheese / eggs / butter. At the time, I was eating A LOT of yogurt and quark. I stopped and now my bloating is much smaller. I believe it is not gone completely because I did not eliminate completely lactose from my diet (the bread I eat has milk) and because I keep drinking sweetened tea (with sucralose). Also, I always suffered from small stomach issues since when I was young.

That's it. I wouldn't list itching as symptom as it is already gone and it is something that happens very rarely (I often go to the gym, I guess it is due to sweating).

Given that I basically have no symptoms (I am also not losing weight and my lift at the gym are progressing at a steady pace) I wouldn't say I have worms. However, the more I look at the pic, the more I don't know what to think.

Thanks for your time.
