I Have A Very Big Hernia That Has Over 80per

I have a very big hernia that has over 80per cent of my bowl in it, I have been home 3 weeks after spending 6 weeks in hospital . I have been told that surgery would kill me I m a 64 yer old lady and I can not believe that there is nothing that can be done for me. I have some medical issues including MS angina!! Asthma but I would think that modern medicin would cope with this. I need help urgently .....
