Many women with PTSD related to sexual trauma to develop chronic pelvic pain. One study is here:
http://www.ncbi.nlm.nih.gov/m/pubmed/17400852/. Books like "the body bears the burden" also detail how trauma can lead to chronic pain of many types. The good part is that the pain can go away with trauma therapy.
Chronic pelvic pain is also very common with endometriosis and can sometimes happen after gynecological surgeries.
Around 23% of women with PTSD do also have drug addictions at some point in their lifetimes. (

That doesn't mean it is okay or good. Rehab facilities, hospitals, and jails have many people on them with PTSD that was worsened by drug addictions and related problems.
Codine is a highly highly addictive medication. It is bad news for the body to take on an on-going basis. It commonly and normally makes many mental health conditions like PTSD much worse. It makes it harder to heal from the physical effects of trauma. It will stop "working" in time, and then you will have all the original pain and the new problem of a drug addiction problem too.
These are some of the normal problems that come with codine use:
"Effects

Long term codine use can actually cause physical pain and make it worse.
There are many drugs like neurontin that can help for long term chronic pelvic pain much more effectively than narcotics and especially codine. If your PCP has kept you on codine for 3 years, frankly, he should lose his license. It's never intended for long term pain relief, but only for 3-5 days use maximum. It is never used for chronic pain of any kind by knowledgeable and good doctors.
I highly recommend you contact a pain medicine doctor and they can help find a better medication to manage the pain until trauma therapy helps as well. There are also nerve blocks that can make the pain go away too. (I used to have chronic pelvic pain myself.) Pain medicine docs handle this kind of problem all the time. I think you will find a huge improvement in the pain and PTSD by working with one.
