all symptoms except loose bowel can be attributed to some sort of pathology related to head and neck region likely within the head but will need more history and clinical evaluation then further a ct scan
seems to me loose stools r all together a different pathology.
straining is there at defeacation however mild it may be and such straining can increase a head pathology.
cannot comment more with just such lithe info.
needs a very close careful look - take her to a specialist neurologist
