If you quit or take a break from drs and tests even if just for a while- I don't see anything wrong with that.

I know I really enjoyed not having to go to drs and PTs week after week, month after month when my wc claim was settled and closed.
It gets very draining esp when you don't really get any answers.

Go with your gut feeling and tell the family you're just taking a break for awhile. Then you decide how long that break will last
