Back pain a year later...

[Avesjsle]

So, a little history first. I was in a bad relationship and my wishes were ignored and i became pregnant, unfourtunatly, i had an abortion... So, about a month later im having severe lower back pains, pinching badly, moving and not moving hurt immensely. A heating pad helped..however im absolutely certain that I had a miscarriage and this pain started it.. I never was able to get the medication or the checkup after the abortion. Then. About 2 weeks now, walking down the street I was attacked from behind. About a day later after the stiffness worse off, the pain starte . Same pinching feeling, sore, aches, tense. And I am 100% certain I'm not pregnant. Could this be nerve damadge? Is something still pinched? Any kind of insight would be greatly appreciated.
