I am Dr Mbong. The symptoms you describe seem to require a visit to the ER to see a Doctor as soon as possible for your symptoms seem to be an onset of an upper urinary tract infection
or obstruction (most probably of the kidney
and its excretory ducts) which needs to be diagnosed early enough and treated appropriately in order to limit any complications.
Azo which you are taking is not sufficient to take care of it.
wish you get well soon,
