Urination problem. Cow milk or nan pro!

My daughter is 8.5 months old. We went to my native its a hot place where within a week's stay she got diarrhoea. It took 2 weeks for her to cure. Post that she is giving pressure to pass urine and sometimes she passes little by little. Checked with doc there he asked to take scan (dysuria). Next day we were back to bangalore thinking that she is getting sick because of climate and environment. It's been 3 days she is still giving pressure to pass urine. Also have a doubt she pees more than 10 times a day even in my native also, is that a problem. Other than this she is active and eating properly. Note: she was on Nan Pro 2 but during diarrhoea started Nusobee 2 as advised by doc and continuing it. Doctors please advise do we need to take scan and also can we start cow milk or Nan pro
