I'm learning Bass for some months now, and what I noticed is that after practising, I'm having sporadic little events of pain on the sides of my fingers, mostly above and below the proximal interphalangeal joints of the fingers. It's nothing really serious, appears randomly and doesn't last very long. I however don't know what that means, as pain (as little as it may be) is usually a sign that something is bad.
So I'd like to know:
- Is this a usual thing to experience (maybe especially in the beginning)?
- Is it connected to the stretching process, as my fingers do have to stretch away from each other quite a distance on the lower frets?
- Is there any finger injury associated with playing bass, that one should be aware of, and that this could be a sign of?
- Might this be a sign that I fret with too much force, or that I don't keep the non-fretting fingers relaxed?
I'm asking very specific questions here, and the reason for that is that other technique / health related issues, like the straight wrist and its connection to carpal-tunnel syndrome or tendonitis, have been covered extensively in the community - Maybe something similar also applies here?
I've been asked to add some pictures of my posture:
Some notes regarding the pictures:
- As one can see, I try to maintain a straight wrist in all the positions (at least if it comes to flexion and extension), and to do that, my thumb shows to the side. This has been a suggestion from this stack-exchange answer.
- I don't stretch the hand like this all the time, but instead only if two consecutive notes make it neccessary to do so.
- The 3rd row shows an alternative for fretting at the 5th fret, the hand is slightly less supinated (which feels better), but at the same time, the "crab" doesn't look symmetric anymore now
- In general, pinky and index finger do apply their force into a different direction than the direction they would flex in, they basically act to the side now - I don't know if that is benefitial.
