I am new here.
I have PA and as a result polyneuropathy with practically constant legs pain. I am on B12 shots for about 2 years.
Now my endo asks me to start with metformin as my insulin ( 11) and leptin ( 40) levels are high.
I am really scared to take metformin as i know that it can affect B12 levels.
Or it doesn't matter if you get shots?
