I had (have?) issues with a collateral which I injured nearly 2 years ago now (middle finger). I couldn't pin it down to one particular side of the finger. Thoughts:
- Rehab is a slow fucker, full 18 months to get totally better (then tweaked that pulley
)
- On the bright side, I could operate with impunity on many grips, it was only some that caused problems, so during that 18 months I did my hardest ever RP and onsight
- Front 2 and Monos caused aggro, as did crimping. Sidepulls were dangerous but sometimes ok and were hard to predict.
- Being pumped was dangerous initially as it encouraged me to torque into holds more
- Front 3 open was very safe
- Mid 2 open I had to learn to hold my hand differently. Instead of dropping my index finger down I had to hold it up, almost like I was using f3 but without the index actually on anything and bent at PIP joint to keep it out of the way. This was particularly important when fingerboarding, seemed less crucial on actual holds. I still hold holds like this on this hand, as a defence mechanism or something. It sounds like this may help you as it keeps the hand more front on and less twisty
- I used tape on each side of the finger then taped in an x pattern, crossing over under the joint, gradually getting further away from the joint as I wound the tape on.
