Hi My Husband Hurt His Back Last Wednesday And Went

Hi my husband hurt his back last Wednesday and went to the chiropractor on Friday. My husband was told he could have a herniated disk in his lower back and to have a cat scan done. However we dont have insurance at the time. Anyways my husband is in lots of pain and his right side of his stomach and lower back (kidney area) is swollen, more so than his left side. I am very worried about him and I just needed a quick possibility of what could be wrong. So I could push him into going to the dr.
