it could be many things, pulled muscle, appendicitis, slipped vetebral disc, nerve problems, severe gas, irritable bowel syndrome, impacted colon etc, etc. thru my exp. alternative medicines work sometimes but at a much slower and subtle pace than traditional medicine. I'm not knocking alternative med. but it has just worked really really slow for me. For instance, I had a severe upper resp. infection, full of phlegm and could barely talk. so this lady recommended this herb called 'Horehound' well i took that faithfully like she said w/no results, so i did a 'hot toddy' and got out tons of phlegm but was still in bad shape. so i went to the doctor and got Antibiotics and it knocked that infection out in a couple of days. so i could always have gone back and taken probiotics to make up for the lost ones in antiobiotic therapy.
