Finger injury

Hi Dr. 8a, The injury I now have is slightly different from what I can find on the forum, so here it goes.. I've had multiple A2 pulley injuries before, also in the finger I now have a problem with. It's the left ring finger since about 3 months. I succesfully conquered the A2 injuries by mainly following the Dave McCleod method (rest initially, slow return to easy climbing, taping, stretching, deep friction massage, cold water method and taking glucosamine). The A2 injuries were giving mild pain by pressing the base of the finger. This one is however a little different, the pain is a little deeper and more to the side (of the middle finger). It developed gradually, the A2 injuries all appeared very sudden (after intensive bouldering) but were also gone very sudden (within a few weeks). I tried the method described above for my injury, but it didn't get better after continuing to climb easy. The A2 injuries actually felt better after a session of mild climbing (I guess because the pulleys where full of blood then and nice and warm), this one felt a little worse and more painful, but it didn't hinder climbing. However I don't trust this injury, so I stopped climbing for about three weeks now (continuing the other treatments), but still no real sign of improvement. Still painful when pressing (but only when pressing quite hard). So could it be something like a A1 or C0 injury or maybe collateral ligament or something? It's not a major injury but I'm really afraid of making it worse. Buddy taping maybe a solution (of course I'm dying to climb again)? I already saw a doctor, but she didn't have much climbing specific knowledge. I will have an echo somewhere in the coming two weeks, maybe that will make some things clear.. I've only been climbing for two years by the way, muscles developed quite fast, but it seems my tendons and pulleys can't keep up handle the load.. Thanks in advance for your reaction.
