How can I help my mother bear the two weeks until surgery for a painful prolapse condition?

The doctor says that the only thing to be done to relieve the pain is to push the prolapse in; there are no suppositories or other local meds. We did put a Lidoderm patch at the base of her spine (it is used 12 hours on/12 hours off) in case it could numb the area a bit and we are also using Lidocaine ointment on the local area. Since she doesn't remember she calls me many times a day to tell me that she's in pain. I feel terrible! We have tried everything to get an earilier appointment but it's just not possible. She is 91 years old with an indomitable will but the depression and the pain are getting to her. We offered small doses of oral painkillers since she can't get up and do her normal activities anyway, but she refused them because they make her woozy. She has a good point in this since the likelihood that she would get out of bed and fall is very high. She does have a live-in aide whose room is on the other side of the living room but the risk of falling (and confusion) is still high.We just started with a home palliative care progam in which a nurse will visit her twice a week. The nursing staff at her residence is also available. I know that I have done everything but it's awful to watch her suffer. Any ideas?
