hi
Salli !
sorry i took my time to answer this although i was tagged here...
what spontaneously comes to my mind are some questions you could ask yourself: how well are you taking care of your right arm, by that i mean, as someone who is left-handed, how much of a relationship have you built with your non-dominant arm? do you feel like you stretch your awareness and consciousness into it enough so that it doesnt have to get your attention with injuries? are you aware of what it wants to say to you? are you taking action in the right direction (in general)? do you feel able to
handle life or is there some area in your life you would rather change by letting go or handling it differently? is there something or someone in your life that you feel is interfering with your intentions and actions and giving you blows that inhibit your actions?
does it resonate with you more to think of your right arm as the actively giving and taking one or the receiving and perceiving one? (that tells you something about how your nervous system is wired, as some (most) left-handed people are "normally" wired regarding brain hemispheres so they tend to be more creative and in-flow by accessing the right brain hemisphere more through working with the left hand, and some are wired "reversed", so the areas of the brain that would be in the right hemisphere in most people are in the left hemisphere in their brains, and vice versa, and so the left hand sensorium and motorics would be wired with the analytical areas of the brain)
other things that might also influence a tendency to injuries is your personal belief system and experience, and the emotional state and background, and sometimes even stuck energy that comes from not allowing the life force to flow or even past trauma.
when stressed and neglecting "filling" the body with attention and mindfulness, people tend to be prone to accidents. it is either a direct reflection of inattentiveness or a call to attention voiced this way by the body.
what other analogy from language comes to mind right now is, you are "armed" you have arms, but that also could imply the arms to be used as weapons or maybe in case of the non-dominant arm a shield. how safe and protected do you feel and is there maybe an emotional aspect in you that feels unsafe with a life circumstance of yours that wants to get your attention through accidents like the above mentioned?
oh and of course maybe it is a call from your body to be aware of how the masculine-feminine energies are embodied in you, usually the right side of the body is associated with masculine energies and the left with feminine, but as said above that can be different in each person so its best if you feel into it and pick what resonates.
i am really curious about how it turns out, have you come to some understanding about these experiences yet?
