I have one I wear on my ankle, but it tarnishes up really quickly. which is worrying. I work on it when it does, and polish it back up (involving not very elegant putting my foot up higher than is comfortable, to put it before my shrine and ask for it to be clean again.
I know that most foot work doesn't specifically hit the feet, but that IS where I've been damaged. I used to be able to wear anything on my feet, and about a year to a year and a half ago, my feet became painful, sensitive, and without being too grim, one foot has clusters of general mankiness in areas all over it. it's horrible. it hurts me, and I have lots of beautiful shoes I can't wear anymore. I work in retail, so I'm always on my feet.
and I can't figure out where it comes from. I really can't. I'm fairly sure it was put on me, but by who, how etc is difficult. and I just want my old, laid back, well behaved feet back. and the way the dime tarnishes up does give me reason to suspect very seriously.
foot track magic is used in Cornish traditional Witchcraft, albeit in a slightly different way, but still, I can't think of anyone who would both have the inclination to damage me like that (I'm a bit abrasive, but nice really) and the ability to do it to me.
I'm worried by this. there's maybe three people I know who have the ability to do this (two for definite, one for maybe) and I would be very hurt if any of them did it, as they are people I care about a lot, and I can't see any reason WHY they would do it. so it's either someone I care about hurting me for a reason I can't understand, or... I don't know. someone I don't know has this ability doing it. although I usually know. or someone playing at throwing this stuff around, only it's affected me so much and so consistantly that it seems unlikely.
sorry for offloading so much. I only really have two people that I can share that with on that level, and that's the two people who definitely have the ability but are like sisters to me, so I would be very hurt if they did. the other had a great deal of natural inclination and a catholic background, but was, at the time we worked together, like a second mother to me. so again, I can't imagine why she'd have done it.
rambling now... but you see why I offloaded here.
