surprised no-one mentioned the 5 of pentacles yet. in the rider waite deck, it features a person who is walking with crutches--I could see this representing someone with leg problems.
possibly the 4 of swords too, as it does represent a time of healing. and looking at the card in the RW deck, I'd wonder if someone has back problems.
also, the 8 cups---the guy walking away in that card is slumped over, like he's depressed. makes me feel like there could be some mental issues there-even perhaps something like bi-polar disease.
the 10 of swords too---most definately. again, perhaps a back problem or spinal cord disability.
good suggestions so far on the other posts.
