Hi friend ..
Thanks for your query to Health Care Magic ..
I read your concern and it seems that Urge to urinate and stinging sensation on tip of penis is most likely to be of Urethritis
( infection and inflammation of urethra
) . It is curable in two days completely . I suggest you to do a Urine test for bacterial growth
before starting antibiotics treatment.
I advice you to be on Tablet Levoflox 500 mg once daily for 5 days and Urispas
to reduce painful sensation .
Drink plenty of water to eliminate bacterial organisms from urine .
Coffee is not the reason for urge to urinate .
Hope this information is useful .
Thanks & Take Care .
