4 year old girl with bladder infection

Hi– My daughter (just turned 4) has suffered from some form of urinary problem for the last 6 or 7 months. It took her a while to potty train, then, just when she seemed to have mastered it, she suddenly started wetting her pants several times per day. She was not bothered by her wet underwear nor would she tell anyone when the accident occurred but would just sit in her wet pants. This was strange to us as she was otherwise fairly particular about her comfort and appearance. Also, she began to wet her bed every night which she had never done before, even while potty training. After a while we noticed a fishy smell to her urine, found she had a bladder infection and had her treated with antibiotics. She seemed to improve for a few days, then the accidents and the infection returned and have remained. Her need to urinate is frequent, almost always urgent and seems to come without warning. She has now gotten in the habit of squatting to squelch the urine flow and explains that if she doesn’t it will “splatter everywhere, ” although often very little actually comes out. She doesn’t seem to be in any pain when she urinates, or if she is it must be very slight as she would surely cry. She is otherwise a happy child and has not suffered any traumatic events. Some other factors notable to her: She is tall, but of average weight, has pale skin (you can see her veins) with delicate features and has heavily lidded/almost sleepy-looking eyes, often with dark circles underneath. She is typically cool, but not cold, and prefers all her covers on her, even when it’s hot. She loves to dress up and will only wear dresses and skirts, preferably ones that “twirl out.” She is almost constantly in fantasy land, pretending to be this character or that. She is very talkative, perceptive and interactive, but always needs someone to be with her. She is extremely affectionate. She loves to sing and often sings while she does her “work” at pre-school. She is very social and participatory at school and is well liked by her classmates. Although generally happy, she is also very cautious and fearful, but not of the dark– in fact she prefers absolute dark because she is more afraid of shadows. She is a light sleeper and has occasional nightmares (usually of something bad happening to her mother) and will actually call out in her sleep. Her fears mostly center around “bad guys” or scary animals that she’s seen in movies which she seems to be fascinated with, even in spite of her fears. She tends to take her pretending very seriously and will even run crying from her sister when her sister pretends to snarl like a tiger or other scary animal. She is very sensitive to bright light and also seems sensitive to smells. She really needs her sleep and will grow crabby towards the late afternoon without a nap. Physically she is active, but tires easily, often complaining that she’s tired of walking, even when we haven’t walked very far. From the beginning she’s also had an unusually clumsy streak, frequently hurting herself and occasionally tripping over her own feet. Typically she is very sweet and sensitive to others’ feelings, but at times can be very impatient, stubborn and controlling-- will launch into a meltdown in a split second and later claim she couldn’t control herself-- and when she is thirsty, watch out– she must have water absolutely immediately. A local naturopath gave her a dose of Nux Vomica and it seemed that the need to urinate was less urgent for a couple of days (although her urine continued to smell fishy), but after that she was back to it being urgent again. Any suggestions would be greatly appreciated. I apologize for the length, but I wanted to provide a full picture.
