Hi,
If you are still reading:
Is the surgery because of a diseased gall bladder or because of gall stones in the passage? Gallstones can cause pain between the shoulder blades.
I ask because different parts of the body have different rulerships.
I was taught that the gall falls under Mars, stones under Saturn/Capricorn, and the gall bladder under Jupiter.
You have an exact Moon-Jupiter in Scorpio opposite natal Venus,.
Mars-Uranus form a YOD figure to natal Venus.
Venus is ruler 6th house of physical complaints.
Saturn makes no hasrsh natal aspects.....except to nodal axis.
The shoulder area falls under Gemini, ruler Mercury, ruler 8th house of surgery, and makes a harsh aspect to natal Pluto (elimination/ replacement physical parts), with Mars the ruler of 12th house (hospitals).
Out of personal interest, did the period between 2010-11 and the following 2 years correspond to a difficult period in life?
Solar Arc Mars would have conjoined natal Jupiter opp. Venus,
Solar Arc Venus was inconjunct natal Jupiter,
during the period that the Saturn return occured.
The time span could have 'planted the seed' (Mars) of a later developing physical complaint.
