I am having cough since January 2017. Its started with fever which goes away after 5 days but cough left. On January my boyfriend release his sperms on my body(chest part ). I am thinking ia my cough because of any infection due to sperms. I am getting treatment since my problem starts, no one Doc able to diagnose my problem and gave me medicine. They day i take Medicine i feel good and when i skip cough starts again. I had all test related to cough(x ray, ct scan, barium swallow, 2d echo,blood test, sputum test) but nothing came out in all reports. Could anyone please suggest me why i am having bad cough.
