Brenda, I think that amputation would be the treatment of last resort. I am only guessing, but I feel that his hospital admission would be for investigation only .Ulcers may be due to vein problems, arterial problems or a combination of both. He may see, or indeed should see, a vascular surgeon who by means of arterograms and venograms see if he is suitable for arterial bypass surgery. Blood and urinalysis is also important. Look on the bright side at this moment in time.
