Hello, Thank you for your query. Based on her symptoms, I would like to rule out aseptic meningitis, venous and arterial thrombus . I recommend : - a physician, neurologist, neurosurgeon consult. -an MRI of the brain with venogram and angiogram to check for insufficiency and blocks. Small tumors.which cause similar symptoms can also be picked up. - CT scan of the abdomen to look for anyass it Tuberculous lesions -blood tests (complete blood count, Erythrocyte sedimentation rate, c-reactive protein, electrolyte levels, kidney and liver function tests. -if all scan are negative and there are no signs if Increased intracranial pressure, aseptic meningitis should be suspected. This usually resolves itself with symptomatic management alone However, diarrhea needs to be treated adequately with fluids and electrolytes. Please seek medical attention right away. Hope this helps and she feels better soon. Please let me know if there is anything else I can help you with.
