I would say "increasingly" instead of "more and more".
Also, depending on the context, Bedrängnis could also mean distress.

Oh, sorry. I thought I had cut and pasted, instead of copying, after having written in the wrong box.

"to get under pressure" is not idiomatic. The phrase is "to COME under pressure", if this is indeed the best translation.
Another possibility is "to become increasingly strained".
More context, as usual, would help. What does "Mittelbereich" refer to?
