Dear Betsy: Alas, that is one of the problems with having a diagnosed anxiety disorder---people can conclude that a physical pain is a product of the anxiety disorder. You have done the correct thing in seeing both your GYN and an internist. It is good that you received several imaging studies (ultrasound and CT of abdomen) in addition to other lab tests.
Obviously I cannot give you any kind of diagnosis, but I can share some impressions based upon your stated history, OK? That the back pain onset with the long car drive, worsens with sitting at the desk (?and computer?), and was improved with chiropractic treatment it would seem most likely that it was an orthopedic issue. The stress of your mom-in-law's untimely demise can impact musculo-skeletal tension which could be a kind of exacerbating factor.
In terms of the pelvic pain, if the cause is not GYN it might be caused by bowel or neurologic conditions:
Bowel caused pain:
? Irritable bowel syndrome ("IBS") can start up after eating, or during stressful events. Bloating, gas, and constipation or diarrhea may be present. Excluding GYN causes, IBS is the most common cause of chronic pelvic pain.
? Diverticulitis is a localized infection in a pouching out section of the bowel.
? Appendicitis pain may manifest with a fever, loss of appetite, and pain focused in the right lower part of the abdomen.
? Crohns disease or inflammatory bowel syndrome may have bloody diarrhea along with the pain.
? Hernias may be evident and uncomfortable when the woman is standing upright, then not apparent when she is lying flat on the exam table.
? Cancer of the bowel, while not a common cause of pelvic pain, needs to be ruled out with a sigmoidoscopy. This is especially important if there are other bowel symptoms such as blood in the stool.
Neurologic sources:
? Myofascial pain creates abdominal wall pain along the lines of major nerve pathways. The area of pain can often be identified very specifically with a finger tip. It is believed that the pain can be instigated by a deeper organ which then refers the pain to the area served by the shared nerve. Performing a straight leg raise (tightens the abdomen) can make the pain worse. Treatment involves injection of the shared nerve with a local anesthetic at the specific site of pain identified by the finger tip.
? Neuroma is a mass, or thickening, of nerve tissue. Often these can arise where there has been trauma to a nerve. In pelvic pain a neuroma can occur in the area of a hysterectomy scar (including inside the vagina), or other surgical scars.
? Pudendal neuropathy results from damage to the pudendal nerve. Women may experience vaginal pain with sex, rectal pain with bowel movements, bladder pain with urination, and pain with sitting.
Less common sources of chronic pelvic pain can include:
? Systemic lupus erythematosis
? Low back injury with pain referred to the abdomen
? Acute intermittent porphyria
Bottom line Betsy, if the pain persists you might consider being seen by a gastroenterologist. If your chiropractor thinks the pain might be from the muscles of the pelvic floor they can refer you to a physical therapist specially trained in women's pelvic pain. As always, is is best to ask your current care providers if they have any referral ideas.
