Ejaculation Pain Post Surgery

I just had inguinal hernia repair surgery three days ago. I had it repaired seven years ago but it came back. This time mesh was used.
Since my surgery, I've noticed a good amount of pain at the point of ejaculation. In addition, there seems to be a constant mild strained/pulling sensation from my scrotum.
I'm posting here today because I am very concerned about this. Has anyone heard of this happening and will it go away?
Should I wait for several weeks to pass before worrying to much about it?
Please help.
