Since its only 2weeks you underwent hystercetomy your internal stitches are stilll in process of healing. In such a case any trauma to the abdomen can be risky especially if its severe. You has excruciating pain following fall of your daughter over your abdomen suggesting it was significant and it might have caused trauma. Also nausea dizziness
following trauma suggest that the pain was severe and it might have resulted in some internal injury
to the extent of some internal bleeding
. I suggest you vistit your operating gynecologist, she would assess the tone of your abdomen along with presence of tenderness and distension. If these signs are present you definitely need to take an ultrasound
to rule out complications following trauma.
