Sick Again, Again, Again!!!

What is going on with my girl?? Alea's school called me today to tell me that she was complaining that it hurt when she went to the restroom and that her back hurt. I took her to the doctor and she has ANOTHER bladder infection. She is on ANOTHER medicine for this. The doctor said he is going to "grow" her cultures from her "sample" and see what he finds. The worst part for Alea seems to be the back pain that goes along with this. My poor girl.
