Sir/Madam,I am 31 & stay in India. I have burning sensation while urinating, have this problem since 3 years now, Urologist suggested urine routine test whose results showed no infections. Actually, this started when I visited a prostitute in Canada 3 years back, I din t have sex with her but just dry kissing and squeezing her body. I din t touch her vagina but she touched my penis with her hand when I had already ejaculated. That was my first and last visit to a pros.I have no other health problem and I am fit and fine. Since, about 2 years my grandmother aged 88 also has burning sensation while urinating. I am worried that she might have caught my infection as we live together and use same toilet. Her urine routine & culture aslo revealed no infection and her pelvis & abdomen scan also was normal and good I seek your best advice
