Maybe it is because I am not a Brit, but, I have a headache from trying to decipher your text. I am a registered nurse, I have diverticulosis, which was diagnosed when I was 43. I had surgery a few days ago, to remove a stone from my ureter. The pain was incredibly intense, causing me, finally, to agree to my husband's pleas to "Get dressed, we are going to the hospital". I kept telling him, "If I am not better tomorrow, I will go". I made that promise 5 days running, before I gave in. Hospitals are okay when I am earning a salary, or, visiting someone. But, when it comes to being the patient, I don't want to go.
Because it also caused UTI symptoms, I asked my doctor to prescribe Cipro and pyridium. It did relieve my UTI symptoms, but, did little for the pain. Within 2 days of taking the last of my antibiotic, I was in the Emergency Department of our local hospital. My Vicodin ES did absolutely nothing for the pain, and, when I discovered that I had a very large stone in my ureter, I totally understood why the pain was relentless. It took a full 10mg of Morphine and Toradol to stop me from moaning and rocking, back and forth.
I have been living with diverticulosis for many years. It is primarily a dietary issue. Stress, and, chronic illnesses can precipitate a very painful bout. My baby sister was killed shortly after I was diagnosed with DD, she lived in Florida. I think I moaned during the entire flight, because I was in such distress. Hearing how my sister was killed, compounded the distress I was already experiencing. For several years, my doctor prescribed dicyclomine - it helped a great deal with the spasms. I also took an orange fiber supplement on a daily basis, usually twice a day. The real change for me came when I made a conscious effort to eat foods that would not upset my digestive tract - and, I think you have to determine what foods you need to avoid. I believe it is different for everybody. I found the internet was very helpful in researching diverticulosis. You can go to a dietician, but, that can be expensive. If you have unanswered questions, you can always pose them here - and, in many other areas of the WEB. My disease is so well controlled, that I have not taken a dicyclomine for about 5 years, and, I no longer need the fiber supplement. Strangely enough, I found that a 20 ounce mug of Ovaltine (with lactose free milk) actually helps to keep me regular.
You mentioned a 23 yo who has DD, and it affected her uterus. They are totally different types of tissue, problems with the uterus generally points to uterine fibroids. Fibroids have absolutely nothing to do with the colon.
You really have to take charge of your own care. You have to determine which foods are okay, and, which you need to avoid. After receiving my diagnosis, I began to keep a journal which listed everything I ate. I also documented my bouts of intestinal upset, pain, and, discomfort. There were times that I was so ill I could not write, so, my husband would take 'dictation'.
This is a chronic illness, it will be with you always. I am living proof that you can learn to live with this illness, it has been more than 5 years since I had an episode.
I hope you are doing better. Maybe you should give Biofeedback a shot. It has helped me in reducing stress. We nurses have very stressful lives - we take care of people in our work, and, often come home to care for family, relatives, and, friends.
Bon chance.
