Due to a masive and invasive brain tumor, I have total glandular atrophy to include the hypothalmus, pituitry, synthroid and adrenal glands. Because of untreatable back pain, I have received 2 epidural injections which have helped reduce the pain and increase mobility. However, at this time, I now have mid and low abdominal pain when I bathroom or reach down to pick something up from the floor, etc. Could this be a side effect of the injections?
