Abnormal lump on hind leg??

Hello,

I have recently bought this beautiful 2year old (in May). She isnt doing anything bar sitting in the field and being fed, and having rugs changed according to weather but I notices she has a large bulge on her left hind. It is on the back of her leg below her hock and is a little warm?

She is horrendous with being boxed and climbs out so I didnt want to keep her in. She is not at all lame or sore and I think she may have thrown a curb? Again let me stress she is not lame but I am thinking that maybe I should put her on a course of bute daily for a week and try a hawthorne embrocation twice daily. This is how I treated my gelding which helped, but he is rising five and it really hasnt stopped him at all....just this filly could have done showing and now she can't? She has no other blemishes which is really frustrating....

Anyone delt with similar?

Pics arent great of it but you get a good idea....
You can make it out just...


What do you think?

Hi it could be Bog spavin which is a soft fluid filled swelling on upper and inner side of the hock.no heat or pain associated with swelling.the treatement for this is to treat it with cold hosing,rest and application of pressure bandage.or it can be Thorough pin that is a swelling under the skin in the tendon sheath the swelling is soft and mobile.it is more common in young horses.the treatment for this is rest,cold hosing and painting with a cooling lotion like ice man gel.drainage by a vet is sometimes necessary.hope I helped you.
