Not sure where you live but around where I live unexplained digestive issues are now becoming first tested for Alpha Gal a tick borne disease caused by chiggers and Lone Star Ticks. It's a simple blood test any Dr. can perform. You might want ot look up Alpha Gal and see if anything there resonates with you and what you are experiencing, in any event good luck and I hope you find out what it going on so you can address it and get back to living a nice fun young life 🙂
