Constipation/Remicade/Stricture?/HELP

I went to the ER yesterday with bad cramps from constipation, HORRID upper abd pain accompanied with nausea and vomitting along with a Remicade reaction. The doctors took an xray and said they saw nothing but a lot of stool yet they didn't once do an xray of my upper abdomen. I was in too much pain to ask about a possile stricture so I just let them treat the reaction. The ER doctor called my GI(my bowels were backed up to where I was almost empacted) and he told me to up my dose of miralax(was already taking two doses everyday with hardly any relief!) So since sunday I've taken 9 doses of miralax, a suppository, fiber supplements, drinking a minnum of 60 ounces of water a day and an hour ago I drank a bottle of that disgusting lemon flavored laxative soda-like drink. Yet I'm barely pushing anything out but thin stools.   

I know I had some colon thickening but this is rediculous! The pain is almost unbearable and around my pelvis/lower stomach and I FEEL the muscles cramp, then I get a sharp pain and I hear a loud gurgle and feel a swish of liquid in my lower abd. and BAM! Time to go to the bathroom. Does this sound like a stricture? The same is happening in my upper abd. Food will sit in my stomach for almost days then BAM. Loud gurgling accompanied by intense pain. My appetite is lowering day by day and I was wondering:

1) How do you diagnose strictures in the Upper GI and lower?

2) Does this sound like a stricture?

3) Can Remicade cause strictures from 'helping' the inflammation subside?

4) Those of you who've had/has blockages/strictures does an all liquid/low residue diet help/has helped you?

5) Can strictures/blockages cause my thin stool?

I'm calling my GI friday because I am tired of this constipation/diarrhea/vomitting/nausea/weight loss deal. I think the flare's gotten better but this pain is different than the usual flare and I'm thinking strictures are the cause. BTW I have Crohn's affecting my upper and lower GI.

Thanks for your reply! I called this morning and he prescribed me a stronger laxative. He also is going to admitt me into te hospital next week when I have my next infusion so they can treat reactions if/when they happen. I also flare every year around Janruary/February so he wants me to fully get out of this flare(almost there!) before the season changes get me and bring me back to stage 1. If I don't have another bowel movement I'm probably going to ask that he order some of the tests you reccomended.

  Back in September I had a 'lobulated mass in cecum' diagnosed by the SBFT and it was all just stool making a pouch in my inflamed cecum, which was also causing the constipation so I'm guesing that's the issue again.

Thanks for the advice clonehead! I tried the liquid diet today and it improved the bloating a lot but still I am having the sharp pains and constipation :/ My doctor prescribed me mineral oil and this other laxative called Kristalose? I have to pick that up at the pharmacy tomorrow.

When I get like this I usually cut my portions and stretch out times between snacking(I don't usually eat 'meals') or I stick to my safe foods that hardly ever hurt me passing through(rice, fish, chicken, rice cakes, peanut butter crackers, chex mix).

I'm going to take your advice this week and see if it helps to do a low residue/mainly liquid diet.

It sounds like a stricture to me. Let us know what the doc says.
I hope you get some relief soon.

yes a sticture can cause constipation, and also ahesions,, when heavy fibouress foods get to a narrow section, it bunches up kinda like an egg shaped clog.. then after a couple of hours it starts to get dried out from digestive juices being reabsorded into the intestine wall,, when i get like this I stop all solid foods and go too liquids,, and stay with them and stool softners, 1 in the A.M. and 1 before bedtime,, if this is happening to you on a regular basis,, it`s probley time to think about surgery.. mine got so bad and I`m hard headed, that i delt with it for 2 years, trips to the ER- every other week.. then it was so bad on time i was put into the hospital for a week then found out my sigmoid busted throgh my pelvic floor,, my 3rd surgery took care of all of that.. try a heating pad on your abdomen the heat will help your body digest and move along the stool that is built up.. and might help to ease the pain by breaking up the gas build up behind the blockage.. try some stool softners but make sure theres no stimulant in them stimulants will cause more pain if your already stopped up.. this is just what happen with me,, you should see you doctor as soon as you can,,
