I need advice locating medical records

[vnv6667]

I was not in the 15th Medical Battalion, but I hope someone will help me.
I was with Co B 1/7.


On or about March 10, 1967, I was injured, small injury, while on patrol outside of a LZ in the Bong Son area. I believe the LZ was LZ English, but not sure. I walked to the 15^th Medical Battalion, I think Co B. I was x-rayed, a piece of shrapnel was removed, a dressing was put on, giving some pills, and I was sent back to my unit.

Problem being is there are no medical records of the event in my Military files. Yes, I have them from St LouisI was treated by B Co 15^th Medical Battalion in October 66 and the record is there.


Did the Battalion keep information of whom and why someone was treated?
If so, what were those records called. Please tell me what information/records I should search/ask for.


Sincerely,
David Polley
