I don't know, I don't think he's considered that option. Will ask him later when he's done with his meeting. You are bringing up something important, I remember him mentioning his dad had a parasite for years, but that was a souvenir from his time in the military.

He had a few exams (ultrasound, horrible examine with a camera as well) and never found something. Covid isn't helping to get him back to doctor either. Health care is horrible here, long waiting lists, communication sucks if there is any. He finally took the step again 2 weeks ago and his doctor is out of office due to covid. I will see if I can convince him to contact him again and explore this option you mentioned, we may be able to find some info and signs that it could be / or exclude it. Thanks!
