New pulley injury?

Just got over a couple pulley injuries in my right hand, but here we go again? First, here's the spot it hurts when I touch my finger:

Edit: it now seems to me that the pain includes the knuckle and runs from the knuckle towards the middle point between the two knuckles (near the circle I drew, just a little further towards the center). Is it normal to have pain on the top of a finger when it's a pulley injury? A physical therapist once told me she thought it is weird that a climber would have an injury on the top because that's where the extensors are, and climbers aren't extending fingers--actually they do the opposite. I should also mention that the last time I injured my hand I couldn't really close my hand into a fist the next day, but today my left hand feels mostly fine. When I injured or tweaked it, I noticed it was hurting to try a move that I presume had injured it (a crimpy roof pull). I traversed onto a 5.7 and climbed that without pain. Today I can hold a tool box and mostly don't feel pain. It does seem to bother me a little when typing. Is it possible to have a really minor pulley strain? Or did I perhaps just bruise my finger by climbing finger cracks? Do you think it's safe to go climb on it and stick to moderate stuff and just stop if anything hurts it?

may have twisted it finger locking. i have the same pain (more like discomfort) except in the back of that knuckle on my index finger. discomfort when typing etc. I did it finger locking harder stuff.

Thanks for the advice. It bothered me all week so I had avoided climbing on it until yesterday. The pain had changed as the week went on. By yesterday it was just hurting to extend the finger (the opposite of what you're doing in climbing), so I went climbing with some tape. I took ibuprofen after climbing. I had iced it all week. Strangely today it feels 100%. I think the climbing actually helped. So glad it's not a pulley injury.
