Dear Jfoster23,
I highly recommend, from my own past experience, that you get a blood test right away to check for: PTH, serum calcium, ionized calcium. I let this go for so long that I ended up having to have Rectocele surgery due to all the constipation causing a hernia in my intestine... you do NOT want to go through all that! Hypercalcemia (usually due to hyperparathyroidism) causes consitipation and can cause some of the other symptoms you have. You owe it to yourself to at least rule hypercalcemia out as a cause of your problems, by getting one simple blood test to test for PTH, and the two calciums I mentioned. I sincerely wish I would have done it years ago. The Rectocele I mentioned was only one of several surgeries I've endured due to calcium damage over the decades. You see, when you have hypercalcemia, your bones are being stripped and then your body won't digest that calcium, so you end up with calcium deposits here and there all over your body, wreaking havoc where-ever they land, damaging muscles, organs, blood, etc. If that turns out not to be the cause, get a colonoscopy. If no results there, get tested for your adrenal glands, your pancreas, etc. Believe me, both IBS and Chostochondritis are what doctors around the nation will diagnose people with when they don't know what the heck is causing their problem... In doctor-speak, those two diagnosis both mean, "I have no idea, but it MIGHT be this." However, usually both IBS and chostochondritis-type pain are in actually just SYMPTOMS of an underlying medical problem... you just have to be an assertive patient to find it. Best wishes!
