I am a 73-year-old female. I strained my middle back 2 weeks ago (and heard or felt a pop), while lifting my 16-year-old granddaughter with CP. Over the 1st week I have took 2 Flexerils, and this week occasional ibuprofen or Tylenol. The meds caused constipation so 2 days ago I stopped all the meds, drink lots of fluids, prune juice, etc., but still not back to normal stools. Now it is hard for me to pee, with a delay in starting and slow stream, except when I first get up, then I can't make it to the bathroom in time. No continence problems during the day. Middle back still hurts.
