I also had PGAD with urinary frequency at one time but I am 99% cured now. I don't know what treatments you have tried. SSRI antidepressants or tricyclic antidepressants can help dampen the symptoms.
I am already married so am not looking for a relationship but I can see why you might think the way you are -- that maybe 2 people with PGAD might be able to help support each other and understand each other in a way no one else could.
We are not match.com here but I know 2 people who met their true love on a pain forum so I guess it's not unheard of to meet up this way. Good luck,
PNE since 2002. Started from weightlifting. PNE surgery from Dr. Bautrant, Oct 2004. Pain now is usually a 0 and I can sit for hours on certain chairs. No longer take medication for PNE. Can work full time and do "The Firm" exercise program. 99% cured from PGAD. PNE surgery was right for me but it might not be for you. Do your research.
