I've been horrifically constipated for days with mild right flank pain that comes and goes.
I finally had a bowel movement this morning and afterwards I had sudden, sharp, extreme pain from my right flank area, but it was also radiating down my back and up my right side. It was awful, I was actually crying into my pillow. I threw up from the pain. This level of pain last for about 20minutes.
I grabbed my TENS Machine as couldn't think of anything else. Had it on full. Pain started to subside after 20mins gradually. It's gone now.
Any ideas? Been back and forth with flank pain and constipation for weeks.
