i went through the same type of thing. it was so bad i couldn't move. i went though tons of tests to see what was wrong with me. my dr diagnosed me with IBS and tried different meds. nothing really worked for me.
i found that i'm not good at dealing with stress. when i'm really stressed out i am so sick. can barely move. i haven't found any triggers anymore that cause the pain, except for stress. where i live now i have 0 to no stress and i'm much better off. occationally my ibs kicks up out of no where.
i hope they find out what is wrong and get you feeling back to normal. till then happy tummy thoughts.
