Welcome to the forum.
Firstly, I want to say sorry for all the stress, pain, and upheaval this accident has caused in your life.
The answer is YES!
I have no scientific evidence, but it makes alot of sense to me. I do remember my basics Physics principles.
After all, the accident is a MAJOR stressor to your body, your "fight or flight" response, and that both of those have created multiple ripple effects in your body, your body's organs, and all their associated relations which have been exponentially magnified.
Also, the "energy shock waves" of having been hit, has traveled not only through your car wrecking it, but through your body - no wonder your body and UC are a wreck - those "shock waves" having been absorbed by your body, your organs, and the world's most sensitive and fine tuned organs, body systems, and cells (that comprises you).
Now as to your second question, And what now?
I have a few thoughts on that:
1) find a good lawyer, make sure everything including the "hell" you've been through and your current medical options (surgery vs...) are well documented.
2) get some other opinions from other GI
3) Before going into surgery, I would search out other alternatives, and there are many for you to try: FMT, LDN
4) There are some easy fixes which will make a huge difference in your symptoms. These are:
a)diet modification (as in gluten and dairy free). Many of us have major issues with these 2.
b)Probiotics are key, are you on any?
c)Supplements such as slippery elm powder, and l-glutamine are very helpful.
d)Vitamin D3, when were you tested last? Low levels are correlated to IBD.
5) And then there's LDN, low dose naltrexone which put me in remission ( to read about this CHEAP drug which has almost no side effects, it's safe for breastfeeding and pregnancy, go to UC Resources page and see the post on LDN). Feel free to email me if you have any questions.
If any of this interests you, there are things IMO that you can control, which will have a direct impact on
your disease, the symptoms you experience and their severity.
I was able to control my UC into remission through various
supplements, probiotics, diet modification, and LDN , low dose
For more info on the protocol which has put me into remission,

I hope you feel better and let us know how we can help
