I saw traces of blood (pinkish) in my semen yesterday. What do I do? Will it go away on its own or is it something worrisome? (although not directly related to this, I was feeling some testicular pain almost 7-8 months ago and my urologist did physical examination, x-ray and color doppler ultrasound and everything was completely normal and pain also went away with some vitamin supplements). But, this trace of blood in semen has made me worried. (has happened only once till now).
