don't put off seeing your doctor. putting things off can make them worse. i am sorry i don't know anything about your hip pain. my husband put off going to the doctors a couple of times, and it almost killed him.
maybe you and your family could attend family counseling. or find a support group for YOU and YOUR family. I am a caregiver, and there are very many trying times. It is hard, but I just put myself in his shoes, and I know it is just as hard on him.
