Pelvic floor

I am not completely sure what the link is, but my weak pelvic floor has almost certainly been the cause of:

a) foul smelling stools

b) constipation/fecal incontinence

c) A wide variety of smells emanating from my skin (including sulfur/rotten eggs and fish)

d) PATM
I feel there is a link, but I am just struggling to connect it all together. I am basing my information off the assumption that the condition is that this condition is a pelvic floor/nerve problem, which will alter your small intestine, stomach, and more. This means that there is a definitive cause, meaning there is a cure. Does anyone else agree? Has anyone found relief or been cured through pelvic exercises?
