Oh Gosh @Blossom1961 ... I really feel for you. It is an oldie but a goodie ..... have you tried prunes?
When I worked in the Gynaecology ward at RNSH, after surgery, the patients were often given Peppermint Water to drink - to make sure all the intestines had straightened out OK before they were allowed to eat solid food ... it sort of percolates thru the whole system & down to the bowel somehow ..... it would move the 'wind' that was backing up in the intestines ..... and that in itself is incredibly painful!
Sadly, it would appear that you have one very big hard bit that doesn't want to squeeze down to a shape that you can pass easily. :( Is one of those they've already give you in the list above, a simple suppository?
Hope something happens SOON! xx
