My mother is experiencing severe pain and seeing an egg shaped item that may be her bladder? Is this possible

Yes, your mother may have pelvic organ prolapse which is a 'dropped' bladder or urterus. This is a common problem seen in women as we age. If the pelvic floor muscle is weak, basically, the organs will drop out. I fit women with a device called a pessary that is put in the vagina and supports the dropped organs. Have her see a gynecologist and ask him about them.
