I am so sorry to hear of your pain and discomfort.
I'm writing because I think you need to go back to your doctor and tell him/her that you are in agony and that you desperately need some help as well as something to manage your pain. Don't let them forget about you. If they don't hear from you, they will assume you are better. Maybe they could provide a referral to a specialist, gastroenterologist, whatever. I would have thought they would have ordered a colonoscopy right away. Believe me, it's not a fun procedure but it's nothing to be excessively upset about. Your health is SO important.
Here are a couple of things that I've found helpful (and reiterate in most of my posts). You may want to:
Do your own research!
Continue to read applicable posts in this forum. Learn as much as you can so you can talk to and understand your doctor(s). There is a fantastic research resource that I've found very helpful called "The First Principles of Gastroenterology": http://gastroresource.com/GITextbook/en/Default.htm. You can either search the whole book or select individual chapters on the left (i.e.: 11- Colon or 13 - Biliary System). For abdominal pain overview, check out: http://www.medicinenet.com/abdominal_pain/article.htm.
Keep a journal!
It's exceptionally useful to keep a journal or a blog and your welcome to read mine if you want (
http://www.medhelp.org/user_journals/index/469934?page=5&personal_page_id=8912&sort_by=date). Everyone who is registered on medhelp has a journal on their home page. It's a great way to review your situation objectively and identify patterns in your symptoms, medications and pain level. Hindsight is 20/20 and keeping a log might help you look at things more objectively over the longer term.
It's really difficult to deal with pain especially when you don't have a diagnosis. You are not alone! Try to stay positive and reach out for support. Talk to your Doctor, your family, friends, co-workers, church or social service volunteers or anyone you feel safe with. Reach out to members of this forum who want to voice their opinions. Remember though, that no one should be giving you medical instructions or medical advice on health-related matters except your health care team.
Take care of yourself. Good luck and Godspeed.
When you do find answers, please post to let everyone know what you found and how you got rid of your symptoms. It gives people on this site hope to hear success stories.
All the best,
Sam
