A horse can actually get mud fever on its belly and upper legs, with no sign of it lower down. Is your horse sore Lauren? Is it possible to post some pics. I appreciate that we aren't by any means expert vets on here - but any soreness and lumps that aren't going away really shouldn't be ignored, and a little forum input and advice surely can't go astray?:smile:
If you are intending to leave it for weeks as opposed to days, before you get a vet opinion I really find that rather worrying. What could be something very minor and easily treated now, could become a huge problem that could take its toll on the horse's whole system if left untreated.
I have to say that often in rescue horses one of the biggest issues is very often a minor problem like mud fever or rain scald that has been ignored and then debilitates the poor horse to the extent that its immune system is compromised and then open to other more serious infections.
This is being said to criticise or worry you, merely to point out the possibilities and the wisdom of getting appropriate professional advise sooner rather than later, for the sake of your finances and Sox's health.:wink:
A year or two down the line you will probably just come across something like this and know instantly what it is, and confidently deal with the issue. We all start somewhere and in the early days we really need to rely more on a vet/farrier or whatever than a friend at the yard.:unsure:
