Noted your history of urine strip showing leucocyte close to 500 but no nitrites, pain in right side of abdomen and back, weight gain of 15 pound in one month, now coughing, metallic taste
in mouth and white phlegm, no medical insurance.
As per the history you have provided I would advise you the following as there must be some problem that needs to be diagnosed perfectly and treated accordingly.
Consult your Doctor for proper clinical evaluation, examination and investigations.
Test of urine in lab: routine, microscopy, culture and sensitivity.
Tests of blood for CBC, sugar, kidney
of abdomen so that propre evaluation of genitourinary system can be done; CT scan
Tests of stool also.
All these will help to get a proper diagnosis.
Get treated accordingly.
Till then take plenty of oral fluids.
Antispasmodic if the pain is persistent and troubling.
Hope I have answered your query. Let me know if I can assist you further.
