Hi. Thanks for your query. Read the history and understood your problem. The history of many surgeries for laminectomy, CSF leaks, drains and now the abdominal pain, headache suggest me to think about the following with indications for investigations and further treatment mentioned together: Get admitted ans this is a serious problem. Investigations: Blood: CBC, Blood culture, Liver, kidney functions. CSF : Culture and sensitivity, routine. -Broad Spectrum antibiotics Supportive and symptomatic treatment. Combined approach of a General Surgeon and Neurosurgeon- insist on this for a better outcome as once the complications occur, one has to be very careful. Do not hesitate to ask for second opinions.
