My husband has been having ongoing symptoms for approximately 9 months now. He experiences gas pains & (bad) gas throughout the day & night (including while sleeping). He has headaches several times a week, & they seem to be worse when his gas is worse. He also complains of extreme fatigue almost non-stop. He has a job where he has to lift heavy items constantly, & he passed his work physical last year & this year. He is a 35 y/o, W/M, who has been a non-smoker for 6 years; he is not overweight (he's about 5' 9"-10" & about 155 lbs, maybe) but he is muscular. He may have an alcoholic drink or beer 1-2x/month. He does not take any medications (other than OTC allergy meds) or any suppliments. The gas & headaches don't seem to coincide wiht any particular food or drink. Do you have any suggestions/recommendations to ease his pain? He recently read about some internal parasite in the intestine that causes similar symptoms (something like "gadin"?). What should we do?
