Sick goat advice

I have a doe about 5 years old who is not well and I 'm not sure what her trouble is. She seems sore when she walks so we trimmed her feet again but they seemed fine. When she squats to urinate she seems shake and weak. Last night after she urinated I notice a small pinkish dot on her hind leg and it appeared there was a bit of discharge under her tail too. I am wondering about a urinary tract infection or stones or something even though all the reading I've done says these are more common in males would really appreciate any advice and/or remedies.

I cant help much or really not at all but would like to say i really hope you can help her out!
