As mike123 says better not listen to us.
I've had it minor in couple of fingers for some 10 years. Until the OA worsened in the fingers I rarely taped. I did not like the splint taping (used only when really bad) and just used to tape individual fingers. Used to stretch fingers alot and to rub along the ligaments between climbs encouraging blood flow, and occasional chilling after a session if really sore. Oh and build up/warm up slowly. I found that regular climbing caused me less pain than infrequent climbing so carried on climbing adjusting how hard I pushed in sessions. Fortunately mine has not worsened with climbing (though OA has).
Now with worsening OA I tape the main fingers individually with the H method every time I climb, still warm up slowly, stretch fingers out straight often, and regularly (incl on days between sessions) use chilling in ice cold water to stimulate blood flow into the fingers.
Does it work? The tape maybe partly psychological but I think it does, and possibly reduces the torquing of the fingers. Otherwise all I can say I am still climbing at the same grades with no obvious worsening of the c ligaments. I don't crimp, or torque the fingers in any deliberate way though. That does limit what you climb. The worst acute pain I get is generally when it's unexpected like the rope catching the fingers sideways, and not by the actual climbing!
