Hi there I understand your concern it may be due to sexually transmitted diseases like gonorrheal infection,Chlamydia trachomatis,Mycoplasma genitalium,Ureaplasma urealyticum...one should be examined clinically with detailed history... You may require investigations like urine routine, urethral swab and microscopic examination... Treatment depends upon weather it's gonococcal or non gonococcal or other underlying cause... Consult nearest physician or urologist for clinical examination they will help you further.
