Healme,
Welcome to the forum.
I love your user name!
I am sorry about your recent diagnosis and your extra systemic symptoms (i.e. joint pains, eye problems, skin rashes).
Those are not uncommon with UC. And it's good you're getting it all checked out.
IMO, it's very important to be on a regimen that works for you, be it certain meds (if they indeed are helpful in reducing your symptoms), supplements and yes, diet as well.
I didn't have much luck with the meds, so I had to find my own way.
And for me, it was a combination of diet modification - as in eating an anti-inflammatory diet, certain supplements, probiotics, and LDN, low dose naltrexone.
Are you on any probiotics?
Any supplements?
Any diet?
If you are interesting in getting more info on what helped put me in remission,

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