Tucking hind under/sitting down

[CLB]

My 7 year old mare has a couple of times tucked her hind underneath her, like horse do when they have there tails washed in cold water. There is no pattern ie before or after work and she has broken put in a sweat so obviously in pain.however if the vet comes out she will look fine and is sound. Originally the physio thought she had pulled her hamstring but this has happened 4 times now over about 4 months...anyone else had this? Thanks

4 times in 4 months, depending on if there appears to be aregular spacing of time between each episode maybe it would be worth speaking to your vet to see if they think it could be hormonal, pain in the ovaries or something? i am just guessing though never heard of anything like that before
