Whatever happened at that moment, it's hard to get away from the Moon-Venus symbolism. Besides the excruciatingly close Moon-Venus on your Sun in your secondary progressions, there was a Moon-Venus conjunction in space that crossed MC a few minutes before your posted. (Transiting Mars was setting.) If you want to pursue further understanding of this, you might find it by digging into Moon-Venus, though I don't have enough insight into your life at the moment to know what that would be.
Were it medical, we'd expect hormonal shifts from it. (This isn't a medical diagnosis.)
Reading the moment of your post as a horary chart with the question, "What happened to me?", the outstanding features are the three passionate, sexual planets Moon, Venus, and Mars right on the angles, Venus closest. I've seen exactly angular Venuses at the moment of a post here many times before and think that, in part, it's a reaching out for social connection and perhaps comfort at the moment, but we can also read it more pointedly for the question. The chart keeps reiterating erotic imagery, e.g., not only the Moon-Venus conjunction culminating but Taurus rising. (From a horary perspective we would expect this to set a general tone of the underlying question.)
Moon is in the 9th house which has no obvious connection to the question unless it is to refer you to a doctor! It applies by < 2° to conjoin Venus, so we'd expect a positive resolution within two units of time (
e.g., two days or two weeks).
Though the inquiry might be regarded as a health inquiry, there is no obvious chart signal of that unless we count the just-set Mars as in the 6th house. (It seems more intimately connected to the 7th, playing up the relationship-eros theme further.) If we take it as health-involving, then it suggests inflammation (and a good few minutes within which to bump one's head).
If we expect hormonal imbalance issues (just an idea, based on all the Moon-Venus) then the concentrated areas are all in the throat (thyroid?) or in the genitals and associated glands.
I think, though, that the chart - read as a horary - is more of a philosophical inquiry. That's the simplest reading of the 9th house Moon. It still sets up for a positive, satisfying resolution within two units of time based on the applying conjunction to Venus.
The angular Mars is separating from its aspects with Saturn and Pluto, suggesting that anything harmful is in the past and on its way out - not in the future. Same with Saturn's sextile to Neptune. Despite the five-planet pile-up of planets (including the forming Saturn-Pluto conjunction) in the 8th, there's no clue you're going to die.
Especially with the partile Sun-Jupiter conjunction in the 8th, I'd expect something more like a purge - something detoxifying occurring - your body eliminating undesirable stuff.
Anyway... I thought I'd try this angle, too. It's sometimes quite useful to think of the moment a question is posted as the birth of a question and "play the game" of horary (but in a more sensible, astrology-based way than horary is usually presented).
