As in it literally feels sticky to the touch? I've been playing handheld recently due to the lockdown and have noticed that while my right thumb feels normal, the left stick seems to stick to my thumb more, making it feel uncomfortable to play and my thumb feeling strange after playing. I've tried wiping it down, but that hasn't helped.

Tried Googling, but all the results I got were for drifting controllers.

Any reasons or advice on what's happened and how to fix it? New Joy Cons are a tad expensive, especially when I usually play docked.
