I took my 6-year-old daughter for a checkup, thinking it to be a bladder infection or a bacteria infection, but the results came back negative. I was then sent to have an ultrasound done on her lower abdomen, kidneys, etc. The doctor reported to me that she has a thickening of the bladder wall and is now referring us/her to a neurologist. I have no clue what is going on. What I thought was just a small check up has now turned into a headache. Please help. FYI my daugter hits her stomach... she says it (lower abdomen) itches and that is the only way to relieve it.
