Yes. I never went to get diagnosed with GE or TE, but my arm was in mucho pain for quite a while there (a year or so ago, thanks to Lux TIMO).
Since then I've been using gut and gut/multi hybrids, flexbar exercises, Band-it armband, etc... until last month when I decided to give gut/poly a go. Just a couple weeks ago I transitioned to full poly again (SP Hyperion--also very comfy), and this week PS Energy and WC Scorpion.
So far, so good. But, I string LOW (43 lbs full poly), and my sticks are sub-60 flex, 18x20 pattern. I still have a backup with gut/multi just in case... but so far so good.
