Okay i'll try not to make this an essay but please read and give me your thoughts and advice:(
I'm 15 and i've just bought my first horse when he was brought into our field he started stomping around etc, and sorting out the pecking order.. but when I took him out for his first ride a few days later, we noticed he was bobbing his head when he was trotting as if to take the pain off his leg so I got off him and he had some swelling on the inside of his leg so we cold hosed it. This was last saturday and we cold hosed it morning and night until wednesday as we went on holiday thursday. We also put him in his own section of field wednesday night because the field has a bit of debris in and is uneven in places. When we went to see him sunday night he still had swelling on his leg and is still bobbing in trot. We've decided to cold hose it morning and night for 5 days to see if it improves and if it doesnt to get a vet out. There's no heat on it, and I havent rode him since saturday.. when I bought him I got all his previous medical documents and he's had nothing like this wrong with him, also a few days before I got him he did a local show jumping competition.
Finally... he's a thoroughbred 16.2hh 19 year old
I don't know much about anything like this so any advice or help would be appreciated also there's no way we can stable him at the moment:( thanks
