Hello, I am writing on behalf of my mother. My mother has been living with MS for over 20 years, but for 8 months she has had persistent stomach aches. Doctors said she has stomach surface thinning, but nothing else. Also, she has electricity between the spinal cord and legs. She has seen several doctors and did several tests (MRI, blood) but no one is able to tell why she has these. Is anyone else suffering from the same symptoms- any advice? Thank you
