I disagree.
It is completely possible to hurt one’s self below 5 Hg (you cannot fall asleep for hours…).
What counts - given your pump is functional (and yours does not seem to) - is
1. You start nice and easy
2. You must never feel pain
3. Your penis must not become dark or cold
4. Any routine must be built up progressively
5. You must never be thinking about discomfort
I think your previous injury with the JES should teach you to do things gradually.
Anyway,
welcome in the club: most veterans suffered a few minor injuries.
Perseverance wins
