gone stiff in hind legs?

[penny3]

hi, new to this but hope someone can help me.
I've had my mare for a few weeks now, she's a 4yr old welsh x. I've been riding her out every few days and up until today she's seemed fine.
Went out on a hack this morning and halfway around noticed she seemed slightly stiff in one of her hind legs, then as we were going down a hill she was limping slightly and not putting much weight onto it. I dismounted and walked her back home, and she seemed to improve as we walked along, but was still stiff in walk. Did a short trot in hand with her and she seemed fine then, not stiff at all, only in walk.
Turned her out in the field at home and she had a good roll, got up and walked off fine.
I'm probably just being paranoid, but just wanted to see if anyone experienced anything similar, and if I should just leave her for a few days or what I should do?
Sorry for long post, but thanks!

Sounds like she has mildly tied up in her muscles over her quarters, it's not always equal. My mare used to tie up in her offside shoulder. Or she may have had a stone in her foot.

Ladylina83: thanks, i think i'll do that. Just she didnt seem much different in herself really, and seems fine now she's back in the field, will check back in a few hours to see how she is.
lhotse: i picked out her feet to see if anything was there, but seemed clear. Thanks for the advice, what did you do/would you do with your mare when this happened?
