Hi Fred55,
Dont worry about reminding me, it was so long ago and i am glad its over
I dont really remember the muscle relaxant but i didnt take it for long to be honest like 2 days maximum, becuase i had to drive to work at that time and it wasnt recommended with the medicine.
What really helped was first of all the exercises and second and most important "dont stress about it" since you already rolled out all other reasons, i think my main problem was that my brain was completely locked on that area of my body causing all the body stress to go there.
I would really recommend searching for pelvic muscle stretching exercises, not strength exercises. And second try to relax about it and see how it will go :)
