Thanks for your query.
As you mentioned you are struggling with difficulty in passing urine and frequency. These finding suggest Urinary tract infection
It may be accompanied with mild fever and pain/burning during urination. It is common infection in men and who are uncircumcised are more at risk to become infected.
Commonly UTI is caused by bacterium E.Coli but it can also be caused by Chlamydia and Mycoplasma
.Bacteria could travel farther up the ureters to infect the kidneys.
You are advised to take plenty of fluids and cranberry juice can help you to heal and prevent such bugs.
Visit your urologist
, who may advise you for CBC, urinanalysis and urine culture to diagnose.
Then UTI can successfully be treated with proper antibiotics with in a week.
Hope it helps.
