can lyme cause severe gastro problems? i have lower and upper issues, but my endoscopy and colonoscopy were both normal. drs mentioned crohn's, but ruled that out since everything looks normal. i have extreme pain, bloating, cramping, loose stools, many food allergies. have had gastro probs for over 15 years, and have had lyme for 8 years, so had some probs prior to the lyme. have also had a few bleeding issues--gastro and menstrual. could lyme cause this, too? not many lyme patients complain of GI probs--just wondering if lyme could be the cause.
