Sometimes I feel I am overreacting, but perhaps there really is a parasite in me. Either way, thank you for all your help thus far!
Ps. I am definitely going to start track my food intake now, stop eating tomatoes and look for those 'tomato skins'/liver flukes. 4 years ago I was diagnosed with' Gilbert Syndrome' due to high bilirubin values in my blood if I remember correctly. Perhaps this diagnose was wrong and it should be liver flukes instead?
