I have to agree with janc... my farrier got the shoes off (even though shes a lami) he told me the abscess needed an exit point and the shoe could well be blocking it (which it was in her case) ... but saying that, hers took ages to drain and showed signs of coming out the corrinary band as well. She went lame on the other leg as well but this was bruising due to the amount of weight bearing this leg had to do. My farrier sent me up to the chemist to buy several tubes of arnica and this did the trick for the 'good leg'. HE also trimmed her feet so she was level at all times (had this done 3 times in the month as her little hoofs were growing like mad at the toes)We had to keep our ponys foot moist as her foot had dried up and was rock hard, so the soaking worked enough to let the abscess out eventually. Our girl was on box rest but interestingly she refused to put her foot on anything but the rubber matting, she could not stand on the straw (possibly because she was so wobbley she felt unsafe balencing on 3 legs...) WE gave 1 sachet of bute but half in morning, half at night. I check your thread everyday to see how your boy is, as I really do feel for you both. But as everyone else has said (and we all have all had lamis with this problem) it is a waiting game and the relief he will feel when it comes out is imense. Take care and keep going, it won't last forever although I know it does feel like that.
