Hello, I read carefully your query and understand your concern. Yoru symptoms seem to be related to a parasite infection such as Giardiasis. Giardiasis is an infection of the intestinal tract by a microscopic parasite called giardia. You get giardiasis by ingesting giardia cysts. These are typically ingested with your food or water. I suggest to do a stool test to confirm the diagnosis. If the diagnosis is confirmed,I suggest to take antiparasitary medication such as metronidazole. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards! Dr.Dorina Gurabardhi General &Family Physician
