Trigger point injections

I have been having constant upper left abdominal pain for over 4 months. The pain is deep inside not muscle pain. A pain doctor tried trigger point injections into my upper left abdomen but it didn't help at all. My abdominal pain is constant, not related to body movements and doesn't change with bowel movements. Food doesn't change the constant abdominal pain. I have short bowel syndrome, had bowel obstruction surgeries in 2019. Doctors don't know how to treat my constant abdominal pain. Doctors are not treating my Short Bowel Syndrome condition either.
