-------This sounds very similar to what happened to me. I fisrtly
developed an intensly inflamed prostate (red hot coal in rectum
sensation) and slowly developed the symptoms of CPPS during this time
(perineal pain etc). The red hot coal sensation was cleared up 2
months later when I was eventually switched to course of doxycycline.

I was left with chronic pelvic pain, (perineal pain; anal pain; pubic
pain; urinary frequency & hesitancy etc.) which was related to chronic
pelvic floor muscle spasm. From what I know, this is originaly a
protective 'splinting' response, but can then become the source of
chronic pelvic pain, even after the original cause (i.e. prostatitis)
has been treated.

I've improved by around 70% as a result of an ongoing course of
myofascial release/pelvic physiotherapy.

This is an excellent article which discusses how damage to pelvic
organs can cause nerve damage resulting in a vicous cycle of increased
pain perception and muscle spasm. He also gives a good discription of
how these changes are reversible by creating a 'stimulation free
period', and uses the example of amputees and phantom limb pain to
illustrate this:
