Hi Deb,
We all have to find our own way of dealing with problems like Crohn's. Whatever you feel works for you carry on with it. I tend to tackle things rather more head-on.
Crohn's manifests its self differently in different people and its presentation can change in a single individual over time. When I first had problems, over twenty years ago, it was mainly diarrhoea, stomach cramps and weight loss. This was mis-diagnosed and treated as IBS. It's only when they took a biopsy did they confirm the diagnosis and start appropriate treatment. I then had more than ten years, drug free and in remission. Seven years ago I developed what I everybody thought was a simple abscess on my backside. As there were no other obvious symptoms as had been seen before, this wasn't treated as Crohn's and once again lack of quick and correct diagnosis leave us where we are today.
The symptoms that you describe all certainly fit with what I and others that I've read about have experienced with Crohn's. For me, pain going to the toilet, no. Fresh blood a little, but this is due to the fistula. Constipation, no, but I do take in quite a lot of fibre as I find this helps me. With others it can be the opposite. Pain under the ribs, no. Pain in the Pelvis/sacroiliac and left thigh, yes. The sacroiliac can be involved in some Crohn's patients. Had an MRI for this earlier in the year, but no problem found. Much improved with the Amitiptyline. Fever/chills at night, no. This is something that you need to tell the Doctors about as it can be a sign of an infection that requires treatment.
I'm assuming that you have had a full work-up of investigations such as MRI, endoscopyu, bloods etc else they would not be talking about anti TNF's and setons? If you continue to experience pain in particular places then you need to be persistent in raising this with you consultants. These things need investigating, even if they don't find anything.
As for diet, I eat pretty much what I like. I also have gastritis and duodonitis, so take Esomeprazole and Gaviscon Advance on a daily basis. I do seem to feel better if I avoid too much fatty food. I have experimented with cutting out, wheat, dairy, caffeine and alcohol. None of these is excluded from my diet, but at home I get by without dairy milk and caffeine. There's no substitute for fresh bread, so that tends to be a weekend treat. Likewise a glass of wine with a meal and the occasional pint of cider. Beer used to be a big aprt of my life when I was younger, but I avoid it now.
Hope that's of some help.
Mark
