I've never done a health reading before! lol I honestly thought it would be a nightmare, but actually, everything I picked up from it seems pretty common sense. The only means I have to take a picture of the reading is my tablet - apologies if the picture is too blurry to read. Here are the cards that popped up for me:
Top: Ace of Cups - Temperance - Magician
Middle: Emperor - 4 of Wands - 9 of Wands
Bottom: 4 of Pentacles - Knight of Cups - 9 of Swords (reversed)
My interpretation: Okay, so right off the bat, we see a lot of cups and flowing water in the mix (pictured, not necessarily the suits), suggesting that you need to increase your water intake... but honestly, that's feels like cheating, because health-wise, hydrating is just good advice for anyone. lol
The 9 of Swords reversed shows that you're waking up / being kept up by the pain on occasion.
The 9 of Wands next to the 4 of Wands seems to (possibly) be saying to watch your alcohol intake (which sort of goes along w/ the whole "stay hydrated" theme). However, having said that, that wasn't the message that my gut was actually picking up on when I read it... I just saw it as something that could be read into it and thought I'd throw it in there just in case. Intuitively, I picked up from the 4 of Wands that you should make a regular habit of stretching (they look like they're stretching in this deck! lol) or possibly take on a light form of dance as an enjoyable exercise. The 9 of Wands in this deck looks like he's hiking, too, by the way, so you might want to consider that as possibility as well.
The Emperor appear over the 4 of coins appears to be your doctor. It seems to suggest that he may either be stubborn / unwilling to work with you in regards to how he approaches your health concerns, or he's merely aiming to maintain your condition rather than improve it. The Magician suggests searching for a new doctor, or (because it's next to Temperance, which is apparently associated with sciatica according to http://www.tarotwikipedia.com/tarot-and-health-issues/
) find a specialist that will directly tackle your sciatica issues.
Lastly, the repetition of the 4's and 9's suggest stability (and not a pleasant one) that is close to the point of really needing to change. The doctor thing really is sticking out to me in this reading.
Hope that was helpful!
