Pelvis Floor Dyssynergia Lower Back Pain

I have been Diagnosed with Pelvis Floor Dyssynergia Type 1 in Anorectal Manometry, Also Got CT Enterology with Normal Study Observation. Gastroenterologist Doctor has Advised Stool Softener for Satisfactory Defecation but it's not helping at all. I am having 4-5 bowel movements a day with only 2 meals a day of smaller Quantity. I make sure that I eat fiber rich diet & not fall short of water intake, still things are not getting better. I am unable to go out at my job due to this. I have been going for Pelvis Floor Therapy but practicing in therapy room and defecating with the same approach at home is completely opposite. In short I am not getting better response. Also I have noticed that occasionally I get lower back pain 1-2 in a month only for 4-5 minutes. When it starts, it reaches at its peak & then goes down & Disappear. So could this has any relation to Dyssynergia. As I have Co-ordination Issue in my Intestine, does this lower back pain also contribute there. Please Suggest Help
