Just diagnosed, and skeptical

Hello everyone,
I am very much new at this, i have never posted anything on a forum before but i am trying to reach out to people that have the same symptoms as me because i just am not getting the answers i want from my doctors.
I am a 22 yr old female. I have had right flank pain since I was 16 yrs old. I was recently diagnosed with IBS but I had to go through so many tests and through so many doctors to get that diagnosis and i am still not sure if thats what is wrong with me. I will write all of the doctors I've seen and the exams and procedures I have undergone to show you guys what all they have rules out on me.
Here is a list of exams/procedures:
Scoliosis X-rays (diagnosed with mild scoliosis), 2 KUB X-rays( negative), 3 CT scans(stationary kidney stone left kidney), an MRI of my entire vertebral column(cervical bulging disk), 2 ultrasounds (negative), physical therapy for muscle spasms(didn't help the pain), endoscopy to look for ulcers (negative), HIDA scan (working 29% just had my GB removed 3 weeks ago).
A list of doctors:
I have been to 2 different family doctors ( different opinions), chiropractor( didn't help flank pain), urologist( said kidneys are fine), gynecologist, gastroenterologist
Symptoms/characteristics :
I hurt every time I am up walking around. The pain is worse in the mornings. It typically stops hurting after I eat a full meal for lunch. I have to carry an ice pack to work with me to survive. I sleep with a heating pad every night. The pain is very sharp in my right flank. The pain seems to "move around" sometimes under my ribs and sometimes right above my hip. It's very strange. The pain is so bad that it makes me light headed. Bowel movements do not seem to help me. Sometimes I believe they make the pain worse. I take spasm medication but I do not think it helps. I have gas really bad so I eat gas-x like candy. I have never thrown up from IBS, but I do get nauseous because the pain is so strong. When the pain is really bad it feels like I need to make a bowel movement but when I try i can not. I also have anxiety horribly bad but I have never Been diagnosed with it but when I am nervous, my pain will show up out of no where
Questions:
Is it possible that if the spasm medication I am taking is a stronger dose it will help the pain, does the medicine even help at all?
Is my anxiety related to this IBS?
If I had a colonoscopy done would it help determine IBS for sure?
Is it typical that IBS only causes pain in the specific Area each time?

Thank you so much for reading. Ask my anything medically I left out?

Thank you! My anti-spasm medication is hyoscyamine 0.125mg. I do not take anything for anxiety because I have never went to a doctor about it. But i know i do have anxiety problems because, i get so nervous when i know i have to go to a doctor that i make myself sick and get mouth ulcers. i also bit my nails all the time. i was nervously waiting to have bloodwork drawn the other day and my side started hurting randomly.The gynecologist said everything was fine, I just had a UTI.

Im a 26 year old male. These are my EXACT symptoms to a T. I have had all kinds of scans and tests as well only to be told that I have IBS. The pain is horrific and I have been miserable very day for the last 5 months. I too have not had a colonoscopy, after the endoscopy none of the doctors I have seen has really suggested it.

Did you end up having one? How is the pain going??

Tash, forgive me if I missed this detail but did you state in your first post that you've had your gall bladder removed? If so, that's an important detail. While I agree you need a colonoscopy (even though you're quite young and this might be why your doctors haven't ordered one), it's the best tool we currently have to view the entire colon. But back to your GB, sometimes when a gall bladder is removed, the bile that is normally processed by the gall bladder is dumped into the GI tract - causing all sorts of problems. Yellow bile output, dumping episodes, cramping, etc. Search back thru old topics here, there are quite a few about trying to live without a GB and have a normal life. Currently I'm on cholestryramine at bedtime, it's supposed to bind with the bile and minimize GI upset (it's helped me about 60% of the time). Sometimes doctors do not always put this together, if you're seeing several, until I explained to my internist that I had my GB removed years ago, he too didn't even consider trying cholestyramine.
