Can you help, please?

I had a vasectomy 2 weeks ago. 5 days after the surgery, my left testicle and pelvic area were extremely swollen and bruised. I revisited with the Dr and he stated that I have a blood clot and that it may take up to a month to get back to normal.

It has now been two weeks since my vasectomy. The bruising is gone and my scrotum is now the normal color. However, my left testicle is the size of an avocado and my pelvic area on the left side is swollen. The pain is mainly at the top of my left testicle and the left pelvic area. When I ejaculate, approximately 1/4th of the semen is black or dark red. Can you please tell me what I may have and what I can do to treat it?
Thanks,
Ryan
