Hi, I Had Surgery For Bleeding Ulcers Back In1971. Cutting

Hi, I had surgery for bleeding ulcers back in1971. Cutting the vegus nerve , I have had many serious health issues . Completely disabling. Vitals always on the money. Confusing the doctors. The doctors and hospitals never can find the cause. What is going on? Now 83 have been suffering from all this for 60 years .Started on active duty in 1957 I was 23 years old. This has ruined my life. Worked this way sick 60 to 70 % of the time.still hurts, Job asked me to retire due to all this. They were afraid I would get hurt worse of get someone else hurt.
